Bug#726530: Bug#780401: (gimp: crashes window manager (fvwm) on closing)
Olaf Dietrich (2015-03-19T15:35:40+0100): Olaf Dietrich (2015-03-18T09:45:07+0100): It seems to be 100% reproducible here; so, if you have any suggestions, I should be able to do some more testing to find out what's going wrong. I did some more testing and now I can reproduce the crash without any user-defined config file (i.e. without a .fvwm/config file on the system). And after some more testing, it is also reproducible within a clean VirtualBox installation of Debian testing. There, I found one more important condition to trigger the crash: Apparently, I must run dpkg-reconfigure locales and set the default locale to None! # dpkg-reconfigure locales -- choose e.g. only [*] en_US.UTF-8 UTF-8 -- set default locale to None -- restart fvwm (no crash without logout/restart) From here on, as before, i.e.: The important bit seems to be that gimp is started from a Unicode xterm (uxterm). In contrast to my earlier message, it is NOT relevant in which desktop (in the pager) gimp is started. * after login (on empty fvwm desk) open the left-mouse-button menu * go to: Debian Menu Applications Terminal Emulators XTerm (Unicode) * start gimp by typing gimp in the Unicode xterm * within gimp: File Open (now open e.g. existing tiff file) File Close View File Quit the last action triggers the fvwm crash If I set the default locale to en_US.UTF-8 (and restart fvwm), then I cannot trigger the crash. Any suggestions how to proceed? (And it seems to be fvwm-specific; I couldn't trigger the crash with e.g. xfce on the same (virtual) system.)

Bug#780401: gimp: crashes window manager (fvwm) on closing
Package: gimp Version: 2.8.14-1+b1 Severity: critical Justification: causes serious data loss gimp crashes the window manager (fvwm) on closing (File Quit), i.e., all applications are aborted and the login screen appears. All currently open data are lost. The problems does not occur always, but very frequently; typically after editing an image, exporting the image (e.g. to jpg), closing the image (without saving in xcf format), and then closing gimp. Error message from kern.log/sys.log: Mar 13 11:23:46 sysname kernel: [123140.740473] x-window-manage[2373]: segfault at 7f76a7774ab0 ip 7f76a601ab95 sp 7fff06f883d0 error 4 in libc-2.19.so[7f76a5fa2000+19f000] (One more window manager peculiarity (I do not know if this is related to the wm crashes): gimp dialogs such as the FileOpen dialog appear without window handles, i.e., cannot be easily moved or resized.)
