So, let me report the solution.
All the files were in an afs filesystem. afs has a limit for the total length of  the filenames per directory. for more details take a look at http://www.inf.ed.ac.uk/systems/AFS/topten.html#Tip13
In my case 10k files with ~160characters per filename were just hitting the limit. The error message is basically misleading.
