Bug#689748: More info, another backtrace
Hello again,
On January 12, 2013, after an update (that upgraded dozens of kde
libraries) and a reboot, I was quickly paging through a pdf document with
evince and the system locked up again. After a hard power-off (holding
the power button down for 5-10 seconds - the only way to regain access)
the crash handler reported it had a backtrace, included below.
An additional data point: xfig also has the illegible font problem.
See previous updates of this bug report re: gbuffy, xtide.
Further explanation on the "moving windows causes a lockup" previously
reported: Moving some windows doesn't cause a lock up, but moving windows
where any part goes off the edge of the screen seems to. Xfig popping up
an explanation window that was partially off-screen (in response to mouse
hover) did cause a lock-up.
The backtrace follows:
Application: KNotify (knotify4), signal: Segmentation fault
Using host libthread_db library "/lib/i386-linux-gnu/i686/cmov/libthread_db.so.1".
