Public bug reported:
Binary package hint: xfce4-panel
xfce4-panel Version: 4.6.0-1ubuntu1~ppa1~intrepid1
It is enough just to start xfce4-panel to trigger the behavior in my
configuration now.
How-to kill the bastard (first time):
Run "xfce4-settings-manager" by Alt-F2 (or in terminal)
Click on "Session and Startup"
Choose the Session tab
Choose xfce4-panel
Click on "Quit Program"
Remember the PID of the xfce4-panel process.
run "kill -9 xxx" where you replace xxx by xfce4-panel's PID.
Then I installed xfce4-panel-dbg and run xfce4-panel by "gdb xfce4-panel",
command "r" there. Stopped it by Ctrl-C and got this backtrace (by command
"bt"):

Then again "quit" xfce4-panel in Sessions and Startup (to prevent it from
autostarting).
Then quited gdb and xfce4-panel by command "q" and replying yes to exit.
