And removing /usr/lib/strigi/strigiea_vcf.so /usr/lib/strigi/strigiea_ics.so
(files from kdepim-strigi-plugins) didn't help either.

I ran a `xmlindexer  -j 1` in my HOME directory and it didn't crashed or gave
mysterious messages.

But still `gdb --args /usr/bin/nepomukservicestub nepomukstrigiservice` gives
me after while:

Program received signal SIGSEGV, Segmentation fault.

So maybe it is more nepomuk related then strigi.
