nepomukservicestub (0.2) on KDE Platform 4.5.00 (KDE 4.5.0) using Qt 4.6.3

- What I was doing when the application crashed:

letting strigi index my files using virtuoso backend (soprano-virtuoso.db ~4.2GB - but I'm working on an even larger DB on another computer and haven't seen a crash so far...)

The crash occurred after have :
- installed latest kernel patch for oS 11.3
- upgraded dbus to version 1.4
Comment 5 Sebastian Trueg 2010-09-09 22:07:33 UTC
@Alvise: can you reproduce this crash? And if so would you be willing to run it through valgrind?
You could do that my disabling Nepomuk in the systemsettings, then start "valgrind -v --log-file=XYZ nepomukservicestub nepomukstorage", and then once you got a ton of output re-enable Nepomuk in the systemsettings.

Comment 11 Evengard 2011-01-21 20:29:02 UTC
Is the bug abbandoned? The crashes persist on KDE 4.5.5
Comment 12 Christoph Feck 2011-02-11 00:39:37 UTC
Evengard, if you can reproduce it, please add a valgrind log.
Comment 13 Evengard 2011-02-11 03:09:38 UTC
in 4.6 it is reproduced VERY rarely, so for now I can't reproduce it with valgrind.
