[Adrian Pop]

Did you get this when trying to attach a file to ticket #3415?
I just did that and everything went fine.
Maybe there is an issue with the German translation of Trac.
You could try to go to:
https://trac.openmodelica.org/OpenModelica/prefs/language
and set it to English US and try to attach a file again.

Closing this since it's a trac bug
