[Nepomuk] Nepomuk linked to shutdown problems and file system corruption in Ubuntu (was Fwd: [Bug 1053783] Re: Ubuntu 12.04 - Stalled shutdown after having had KAlarm opened; with package info.

"File system corruption" is a little extreme though - from the bug report

unmounted. It may still be a real bug needing fixing though. I asked
something in the launchpad.
