I switched from Plastik to Redmond, and still observed the problem. I got an identical backtrace (except the thread number, of course).
Also every time I log in to KDE, I get the KPersonalizer window. Whether I go through the wizard or quit it, KPersonalizer reappears on the next boot (maybe login too, I'm not sure). This could be a related problem or not, I'm not really sure. I was doing some work compiling some KDE components (RSIBreak) and may have modified system files somehow, though I'm unsure if this is the case. I realize this isn't a support forum, so don't worry about trying to resolve the issue. I'm just reporting the backtrace in the hopes that if the problem does lie in the system, not my muckings around in it, then it can be prevented for other users. -- closing a window causes kwin to sigsegv https://launchpad.net/bugs/57782 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
