Bug 285776

Application: nepomukservicestub (0.2)
KDE Platform Version: 4.6.5 (4.6.5)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-12-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
- Unusual behavior I noticed:
I guess that nepomuk crashs when he indexing incomplete saved files. Files who just jet are written to de disc when nepomuk will read them.

The crash can be reproduced every time.

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