[Bug 442144] [NEW] Xorg crashes with SIG 11 in FindGlyphRef

 

Public bug reported:

Binary package hint: xserver-xorg-video-intel

Dear all,

when using some applications (easiest to reproduce is kmail, when
writing a new mail) X crashes with Signal 11.

Backtrace is:

Actual result:

- Xorg crashes and I am back at the login screen

Unfortunately i am not 100% sure which package causes this, whether it
is Xorg, the intel driver or Qt. But my best guess was the intel driver,
as I only saw it on my intel system so far.

Hope you are able to reproduce and fix this. 
Just ask if you need further information. 

Kind regards

Christian
