*** Bug 312842 has been marked as a duplicate of this bug. *** Created attachment 76971 [details]
New crash information added by DrKonqi
nepomukservicestub (0.1.0) on KDE Platform 4.10.00 using Qt 4.8.2
- What I was doing when the application crashed: nepomuk service stub crashes on startup. if I close the crash report window it reappears with a new PID value. However the virtuoso-t process is running and using a significant amount of CPU (never less than 20%). This all started after the upgrade to KDE 4.10.

Git commit a3b9c773f2af81d6313757c8158d912c60cc7d64 by Simeon Bird. Committed on 16/02/2013 at 19:59. Pushed by sbird into branch 'KDE/4.10'. Filewatch: do not try to watch empty paths. In slotDeviceMounted, we find the mountPath to watch using entry->MountPath. However, if the removable device could not be viewed as a Solid::DeviceType::StorageAccess, mountPath returns QString(). We would then try to watch an empty folder. In shouldFolderBeWatched we would try to split the empty string, resulting in an empty list, and take the last component of this list, leading to an invalid pointer and a crash. The fix is two-fold: First, check for empty mountPath in slotDeviceMounted and do not try to watch it. Second, check that the split path is not empty in shouldFolderBeWatched before taking the last component.

- What I was doing when the application crashed: I did decided to see if the app had been fixed. It has crash everytime it was started for at least a month or more. So I enabled indexing and within seconds the crash report opened.

- What I was doing when the application crashed:
first run after installation of new PC. I just logged onto the desktop - nothing else - now I cannot even get rid of the crash notification. I can click all night on the Close button but it gets a bit repetitive. Is that another bug?
