Comment 1 Robert Knight 2007-12-07 19:46:45 UTC
Hello,

The code has changed since the original report so the line numbers in the backtrace are no longer correct.

Can you get a version of the backtrace from a more recent build?
Comment 2 Matthias Kretz 2007-12-07 19:51:44 UTC
No, I was not able to reproduce the crash again.

Either look at the old code or close this bug until somebody can reproduce it.
Comment 3 Robert Knight 2007-12-08 00:42:19 UTC
Okay.  I found a possible out of bounds array access in TerminalDisplay::paintFilters(), fixed by revision #746132, although I don't know if it was the cause of the problem.

Closing as REMIND.  Please re-open if it happens again.
Comment 4 Jonathan Thomas 2009-04-26 14:24:54 UTC
This has been reported to us at Ubuntu in KDE 4.2.2 (https://launchpad.net/bugs/367262)

The reporter reported this happening when returning from fullscreen mode.
