No, not yet. I wanted to avoid hours of strace or debugging sessions
with the chance of making a very dump known error. While waiting I
kicked out some other bugs in my code and today ... it can't be
reproduced.

When the error has been occuring it reproducably failed hanging in the
xterm on the char 'ß', verified by renaming the first file with that
char in the name and seeing the program hang on the second one. I had to
use CTRL-c to stop it. Other german chars, 'umlauts', where working fine
although being written to the xterm using a wrong char set.

The bugs fixed afterwards have no relation to encoding. One of them was
handing the wrong container to a deeper recursion level, but there are
no dangerous pointer handlings or similar involved. Only plain type
checked class instances, none of them got lost, only the wrong one was
filled with data. I have no idea what happened.

Sorry for the noise and thank you!
