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

[Ignacio Serantes]

Hi,

I test this patch in a test system using an updated Chakra with KDE 4.7.2
and sadly don't works. There is no crash window but nepomuksearch service is
crashing and this is the output of the last crash:

<-------------------------------------------->

Application '/usr/bin/nepomukservicestub nepomukqueryservice' crashed to
often. Giving up!
<-------------------------------------------->

This is the test system I'm using:
- Chakra i686 linux running in Virtual Box and updated today to KDE 4.7.2.
- One folder named /home/ignacio/indexable/ indexed by strigi with three
files. Only this folder is indexed.
- One file named "test 1.txt" tagged with "test" and "test 1".
- One file named "test_2.txt" tagged with "test" and "test 2".
- One file named "テスト 3.txt" tagged with "test" and "テスト 3".

When I search using krunner, typing "test"and "テスト", nepomukqueryservice
crash.
