Application: systemsettings (1.0) KDE Platform Version: 4.6.2 (4.6.2) Qt Version: 4.7.2 Operating System: Linux 2.6.38-8-generic-pae i686 Distribution: Ubuntu 11.04 -- Information about the crash: - What I was doing when the application crashed: I opened the systemsettings program when I liked to start the "filetype association" the application crashed. This behaviour occurs everytime when I do this. Other sections like users still work - Unusual behavior I noticed: I think it started after I installed VirtualBox (but not absolutelly sure). After that the icons on my deskop won't start the progams anymore. Everytime a file selection dialog pops up. Same for the program icons in the task bar. After restart I got many windows with errors about missing mime types (could not be found): „inode/directory“ „inode/blockdevice“ „inode/chardevice“ „inode/socket“ „inode/fifo“ „application/x-shellscript“ „application/x-executable“ „application/x-desktop“ and an single window with an error for: „application/octet-stream“ Actually this was the reason to look into the "filetype associations". Although the akonadi Program crashes at startup! The crash can be reproduced every time. -- Backtrace: Application: Systemeinstellungen (systemsettings), signal: Segmentation fault [Current thread is 1 (Thread 0xb58de710 (LWP 7055))] Thread 2 (Thread 0xb0ac4b70 (LWP 7056)): #0 0xb771d424 in __kernel_vsyscall () #1 0xb6184f76 in __poll (fds=0xb0101208, nfds=1, timeout=-1) at ../sysdeps/unix/sysv/linux/poll.c:87 #2 0xb5bc084b in g_poll () from /lib/i386-linux-gnu/libglib-2.0.so.0 #3 0xb5bb01af in ??

You appear to have a null mimetype in the list returned by KMimeType::allMimeTypes(). Can you zip up your ~/.local/share/mime and attach it to the bug report? There must be something in there that triggers this issue. Technically it could come from /usr/share/mime too, but I guess it's more likely to be a "local settings" issue than a broken system package (which would affect many more people).

*** Bug 315132 has been marked as a duplicate of this bug. ***
David, does comment #6 and comment #7 provide enough information to investigate the cause for the crash? The latest duplicate is from the same reporter, so he can probably provide updated information. It could also be caused by bleachbit, corrupting the sycoca file. Gabriele, do you use "bleachbit" tool?
No, I've never used bleachbit. Don't know if it's related, I have some kde programs compiled from git. This kind of crashes usually happens in the days following the upgrading of kde. For instance, two days ago I've upgraded to kde 4.10 using a ppa archive. And I've used one the program (kdevelop) that have been compiled against previous version of kde (btw it crashed the very first time it started, but without useful info in the trace log). Yesterday fileytpe associations crashes every time I opened it for several runs. Today it does not crashes anymore, without changing anything. Is there some form of "cleaning" or "recovering" of sycoca in case of crashes?
You can recreate the sycoca file with "kbuildsycoca4 --noincremental" in Konsole.

Dear Bug Submitter, This bug has been stagnant for a long time. Could you help us out and re-test if the bug is valid in the latest version? I am setting the status to NEEDSINFO pending your response, please change the Status back to REPORTED when you respond. Thank you for helping us make KDE software even better for everyone!
The bug seems solved in last KDE version.
Thanks for the update!
