if have a rather long answer this time, this is a test run i made today.
i wanted to include full details. i'm wondering if there is still
something these files have in common. first i created some test files on
a spare partition with "touch":

1 fatal corruptions were detected in FileSystem. Run with --build-fs
option to fix them.
*-*-*-*-*-*-*-*-*-*
I know that this 1 fatal corruption appeared after "touching" the
filename "BewerbungFürAnwaltsbüro.doc", because i always did (touch;
umount; fsck.reiser4; mount; touch...). all other files did not seem to
cause fatal corruption. So i wanted to see of only this filename gets
moved to lost+found.

Hey, 8 files are trash now! And look at the filenames in lost+found! I
can't even rm these files because they contain these weird characters...
So i guess i'll have to reformat.
