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? 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. 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. 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.
