There is a related problem with panel crashing that I just reproduced on a clean test user and that at least produces some capturable errors when launching xfce4-panel from the terminal. That error information is attached as panel-error-from-terminal. To explain what is happening there let me lay out the steps to reproduce the configuration described in the initial report. 1) (from the console) completely move aside my user's ~/.config/xfce4/xfconf directory 2) (from the console) completely remove my user's ~/.cache/sessions directory 3) log in 4) select Use default config from the panel first run dialogue box The resulting xfce4-panel xml file is attached as xfce4-panel-From-Empty-XFconf-Selecting-Default-Config.xml This file is different from the one at /etc/xdg/xfce4/panel/default.xml in two ways. First, panel 0 and panel 1 are listed in reverse order when the config is moved to my user and second, the entire contents of panel 0's config have been replaced with property name=panel-0 type=empty property name=position type=string value=p=0;x=100;y=100/ /property 5) (from the console) replace my test user's xfce4-panel config file with the one created for my user in step #4 6) (from the console) completely remove my test user's .cache/sessions 7) log in as my test user At this point my test user has the same configuration-less single floating panel as my user. This floating panel regularly crashes if moved, especially to the screen edges. So to generate the panel error message attached, I simply move the floating panel, watch it crash, then launch it again from the terminal and move this new panel, again watching it crash. That is where the contents of panel-error-from-terminal come from. If I remove my user from the equation everything works fine. I can clobber the test user's xfconf files and session cache, log in, and selecting the default config corectly copies over the deault settings. Those settings diff cleanly against the one in /etc and create normally populated and positioned panels for the test user. So something outside of my user's .xfconf or session cache is causing the default panel settings to be mangled when moved over. I'm not quite sure where to look for that though. -Ian xfce4-panel-Message: no valid position defined: (null) *** glibc detected *** xfce4-panel: double free or corruption (fasttop): 0xb96e30c0 *** === Backtrace: = /lib/i386-linux-gnu/i686/cmov/libc.so.6(+0x6aac1)[0xb6cc0ac1] /lib/i386-linux-gnu/i686/cmov/libc.so.6(+0x6c328)[0xb6cc2328] /lib/i386-linux-gnu/i686/cmov/libc.so.6(cfree+0x6d)[0xb6cc53dd] /lib/i386-linux-gnu/libdbus-1.so.3(dbus_free+0x1f)[0xb709849f] === Memory map: b64e3000-b64ff000 r-xp fe:01 539701 /lib/i386-linux-gnu/libgcc_s.so.1 b64ff000-b650 rw-p 0001b000 fe:01 539701 /lib/i386-linux-gnu/libgcc_s.so.1 b650-b6521000 rw-p 00:00 0 b6521000-b660 ---p 00:00 0 b662b000-b6635000 r-xp fe:01 524383 /lib/i386-linux-gnu/i686/cmov/libnss_files-2.13.so b6635000-b6636000 r--p 9000 fe:01 524383 /lib/i386-linux-gnu/i686/cmov/libnss_files-2.13.so b6636000-b6637000 rw-p a000 fe:01 524383 /lib/i386-linux-gnu/i686/cmov/libnss_files-2.13.so b6637000-b664 r-xp fe:01 524295 /lib/i386-linux-gnu/i686/cmov/libnss_nis-2.13.so b664-b6641000 r--p 8000 fe:01 524295 /lib/i386-linux-gnu/i686/cmov/libnss_nis-2.13.so b6641000-b6642000 rw-p 9000 fe:01 524295 /lib/i386-linux-gnu/i686/cmov/libnss_nis-2.13.so b6642000-b6655000 r-xp fe:01 524371 /lib/i386-linux-gnu/i686/cmov/libnsl-2.13.so b6655000-b6656000 r--p 00012000 fe:01 524371 /lib/i386-linux-gnu/i686/cmov/libnsl-2.13.so b6656000-b6657000 rw-p 00013000 fe:01 524371 /lib/i386-linux-gnu/i686/cmov/libnsl-2.13.so b6657000-b6659000 rw-p 00:00 0 b6659000-b665f000 r-xp fe:01 524369 /lib/i386-linux-gnu/i686/cmov/libnss_compat-2.13.so b665f000-b666 r--p 5000 fe:01 524369 /lib/i386-linux-gnu/i686/cmov/libnss_compat-2.13.so b666-b6661000 rw-p 6000 fe:01 524369 /lib/i386-linux-gnu/i686/cmov/libnss_compat-2.13.so b6661000-b67d8000 r--p fe:01 138974 /usr/lib/locale/locale-archive b67d8000-b67db000 rw-p 00:00 0 b67db000-b67e r-xp fe:01 143570 /usr/lib/i386-linux-gnu/libXdmcp.so.6.0.0 b67e-b67e1000 rw-p 4000 fe:01 143570 /usr/lib/i386-linux-gnu/libXdmcp.so.6.0.0 b67e1000-b67e3000 r-xp fe:01 143562 /usr/lib/i386-linux-gnu/libXau.so.6.0.0 b67e3000-b67e4000 rw-p 1000 fe:01 143562 /usr/lib/i386-linux-gnu/libXau.so.6.0.0 b67e4000-b67e5000 r-xp fe:01 153401 /usr/lib/i386-linux-gnu/libX11-xcb.so.1.0.0 b67e5000-b67e6000 rw-p fe:01 153401

I had originally two panels with various widgets and locations. The first time I restarted after the upgrade, I was down to one panel, floating near the top left of the screen, where no panel had previously been located. The second panel was gone, all widgets and other settings were gone from the one panel. As far as I could tell, the original .xml for the panel was fine. Despite adding new items and reconfiguring the panel, subsequent restarts result in the same single blank panel. I have tried copying the default settings from /etc/xdg/xfce4/panel/default.xml to no avail. I have also tried just removing the xfce4-panel.xml file, removing the entire ~/.config/xfce4 directory, and between all of these attempts, been deleting my ~/.cache/sessions directory. If I create a new user, everything seems to work fine. If I delete the new user's xfce4-panel.xml and replace it with the default from /etc, I get the default panel layout as expected. If I do the same thing with my user, I get a broken version of the default file. Copying that file to the test user's ~/.config directory results in the same single broken panel behavior for the test user. So you're saying that the /etc/xdg/xfce4/panel/default.xml file is broken and will even break users configuration even though they override the default one? I didn't notice that so it might still be config-dependent, but that's indeed bad. Regards, -- Yves-Alexis signature.asc Description: This is a digitally signed message part
