Bug 306920

Summary: Nepomuk crashes on shutdown
Product: nepomuk Reporter: Simon King <simon.king>
Component: generalAssignee: Nepomuk Bugs Coordination <nepomuk-bugs>
Status: RESOLVED DUPLICATE    
Severity: crash CC: xa1
Priority: NOR    
Version: unspecified   
Target Milestone: ---   
Platform: openSUSE   
OS: Linux   
Latest Commit: Version Fixed In:

Description Simon King 2012-09-17 10:14:45 UTC 
Application: nepomukservicestub (0.2)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.8.1
Operating System: Linux 3.1.10-1.16-desktop x86_64
Distribution: "openSUSE 12.1 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:

I was shutting down the computer.

The assistant suggested several bug reports as potential duplicates. However, I am not convinced that one of them fits: The crash does not occur on "almost every shutdown" (so far it happened only once).
And another suggested duplicate has already been fixed in a stable release - so, it shouldn't occur, because my OpenSuse installation is up to date, if I am not mistaken.

-- Backtrace:
Application: Nepomuk-Dienst (nepomukservicestub), signal: Segmentation fault
