"The crash can be reproduced some of the time." how, exactly? looking at the backtrace: evidently something is being pasted to the desktop with a middle click? and then it looks like ksycoca is exploding when asked for items that match a mimetype and it has to go off and rebuild the database, during QProcess handling. puzzling. I had it happen twice. One time I was simply moving the mouse out of the window (while pressing a mice button perhaps). I have 'focus follows mouse'. There might have been a very long string in the paste buffer. I wish I could narrow down a bit more myself. *** Bug 238496 has been marked as a duplicate of this bug. *** This crash report is against an old kde version. Can you reproduce this bug with a newer version? If yes, please reopen the bug. Thank you |
