Plasma crashes on shutdown (via kickoff -leave - shutdown) and two kcrash windows pop-up - backtraces from both below. Once the two kcrash windows are closed, shutdown proceeds normally. I get this about one in five shutdowns. I ususally have skype, akregator and network manager in the systray, but all other applications closed. I have had the same crash with them all closed though, and haven't been able to reliably repeat this. Backtraces below in case they are useful. Please let me know if/how I can provide any more information Thanks.

what version of plasma? this is very important as this sounds like a bug that has been fixed already for 4.1.
Hi, I was on 816-something. I've just updated to 818856. I'll keep playing with it, if its still there I'll get an occurence soon enough and post a confirmation. cheers.
*** Bug 163964 has been marked as a duplicate of this bug. ***
probably fixed with r820991
hi mstarkey, is this still reproducable for you with beta2?
updated my build and haven't been able to duplicate ever since, so marking as resolved.
