Strigi crashes

[Sonic]

Hello

I started using Nepomuk/Strigi recently and enabled indexing. I observed 
that after a while, the indexing icon (in the systray) is vanishing. 
When I check in System Settings, it shows that Strigi is disabled. If I 
enable it again, it runs for a couple of seconds (the icon in the 
systray appears) and again vanishes.

Instead of enabling it in System Settings, I started strigi from 
terminal by doing:
nepomukservicestub nepomukstrigiservice

The same observations repeated. But when strigi crashed, I got the 
following in the terminal:

==============================


Can anybody please explain what's happening here? Is it that a 
problematic file is causing strigi to crash? If that's the case, how do 
I find the culprit file?

I run Fedora 14 that was updated this morning ('yum update' from regular 
stable repos).
