OK, I guessed, just grasping at straws...

Yes and yes -> android_upload.keystore

Problem is, the SAME keystore file worked on Matthias machine (and probably others)
without any problem, but not on mine, so there must be something in my setup that 
is causing this error.

Unfortunately LC does not give furhter infos about this error/problem.
What can I do? 
Can I "hook" somewhere into the creation process to get better info?
