Hi Almut,
first of all, thanks for your reply. I did what you said, now I sit here
with loads of output. After checking it, I guess the interesting stuff
is there (at the end of the log):
---------SNIP---------------

-----------------
Before this, it opens other files in /usr/share/phpmyadmin/libraries,
but works ok. Maybe someone could help here? ;)
