Cant delete mail! (repost)

[krille]

I can't delete any mail in roundcube.
I can however move mail between boxes, but not delete anything.

Any suggestions?

I've not seen any solution or answers to this problem, is everyone ignoring it?

It really is a dealbreaker, roundcube is useless if my users can't delete mail!

Running latest version on OS X 10.5.1 server.
Everything else works.
