[Nepomuk] BUG?: IN013: Wide source charset specified, but the supplied string not wide

[Sebastian Trüg]

Oh, yeah, this is unrelated to my patch. The query service from
nepomuk-core also crashes for me with some weird error I cnanot make any
sense of yet.
Strangely enough the same service with the exact same code from
kde-runtime does not crash... :/

C++ is weird indeed. :D

Cheers,
Sebastian
