The crash is in KSharedDataCache, but this > Plasma seems to restart immediately (I can see the panel dissapearing and then reappearing again) Sounds as if not only kwin but also plasma-desktop crashed and that sounds less like a random segfault in the caching system. Overmore, this: > I have to double click everything instead of simply selecting (something on Task manager or any other widgets). Is not only plasma-desktop (stressing the assumption above), but really weird. I assume kwin restarted as well (so you could move windows around etc.)? -> Do you run this in a virtual machine or with a parallel login (ie. you logged in on VT7 and then started a new session on VT8 and logged in as the same user or something like that)? *** This bug has been marked as a duplicate of bug 305654 *** (In reply to comment #1) > Overmore, this: > > I have to double click everything instead of simply selecting (something on Task manager or any other widgets). > Is not only plasma-desktop (stressing the assumption above), but really weird. Yeah, that was weird, so I've tried clicking on things again (before and after inducing the crash). Turns out the problem I have with the Task Manager is present even before inducing the crash. And I have no problems with the System Tray and most of the other widgets (what I mistook for a widget unrelated to Task Manager were actually parts of Task Manager, launchers for apps that show only when these apps aren't running). So I'm sorry for not being thorough and for the initial confusion. However, there's another widget that acts weird: Lancelot launcher. As I click on it, it crashes (even without kwin crashing first so it may not be related to this bug but I will attach the backtrace here first), and then if I click on it again, it simply doesn't work. The button animation is there as I click it, but no drop down comes out. > I assume kwin restarted as well (so you could move windows around etc.)? Yes, I could move windows, just trying to use Alt-Tab again would result in the same kind of crash. > -> Do you run this in a virtual machine or with a parallel login (ie. you logged in on VT7 and then started a new > session on VT8 and logged in as the same user or something like that)? Not a virtual machine and just one graphical/KDE login. Also, in the meantime, I've tried exploring System Settings a bit and found out that I can't open Desktop Theme settings. System Settings crashes (will attach the bugtrace). But playing with System Settings did bring results. I tried changing the Task Switcher and it's options. At first it didn't work (I would press Apply and not close System Settings, and Kwin would still crash on Alt-Tab), but out of a sudden, after some time and one suspend2RAM, the Task Switcher seems to work again. :| Will report in a few days if this was just a false alarm or if it somehow did fix itself. P.S. I always try not to purge ~/.kde or even just Plasma settings as I don't want to rearrange the desktop the way I like it every time an update comes, but I've been sticking to the current settings maybe for far to long and maybe all my troubles would go away if I could start from a fresh KDE desktop.

Desktop Theme settings crash
Created attachment 82139 [details] System Settings crashing again I've have crashed System Settings now just by selecting a different Task Switcher (Compact). I didn't even have to apply the settings. I discovered I got my /var partition filled up, and after cleaning it, I can now select different Task Switchers without crashing System Settings. However, going to Desktop Theme settings still crashes System Settings (attachment #82138 [details]). It's always the same crash. - Do you use bleachbit? - Is /var/tmp/kdecache-`whoami` on a filesystem with limited size (tmpfs)? If neither does moving /var/tmp/kdecache-`whoami` aside (do please not delete it!), logging out and back in "resolve" this issue? *** Bug 330857 has been marked as a duplicate of this bug. *** |
