empty SCM error

Hello Forum,

I recently installed OO Studio 10.50 and tried to connect to our SVN-Repository. Turtoise-SVN works, but the OO Studio internal SCM does not work. In the Studio.log there is a line about the imported certificate, but then this appeares:

2016-10-26 09:04:43,419 ERROR ScmMessagesPanel.writeScmCommands:277 SCM message:

And the message is empty. When starting the OO Studio the following erros appear:
