Created attachment 108354 [details] Information about the bug including backtrace generated from the crash reporting assistant(it refuses to submit the bug report,error code 410,saying that i must login when i had previously logged in) -- Information about the crash: - What I was doing when the application crashed: Kwin crashes on startup and also when i am using my laptop(randomly) I checked various bugs including the ones involving intel graphics drivers (my laptop gpu is Mobile Intel® GM45 Express Chipset) for possible duplicates and even applied some fixes yet kwin keeps crashing so this is not a duplicate. The crashes are frequent almost everytime i use kde - Unusual behavior I noticed: The application launcher when clicked floats(the application launcher does not touch the status bar) and sometimes do not respond during the crash until i restart kwin The crash can be reproduced sometimes.
Unfortunately the backtrace is missing debug symbols. If you are able to reproduce please install debug packages and attach a new backtrace. For more information see https://wiki.debian.org/HowToGetABacktrace

Created attachment 108433 [details] Two backtraces with debug symbols one gotten using the bt command and the other gotten using the bt full command in gdb
