It seems to be a problem of SVN for not being able to process Polish characters in comment. In the coming release, we will add checking to this. If have error, we will ask if you want to commit by skipping the comment. We’ll inform you when it is released.
VP Suite 3.1 Service Pack 1 has been released. Although the problem is inevitable, we now added checking, and asked if user want to commit by skipping the comment. If you are running VP Suite 3.1, you can advance to Service Pack 1 by running the Updater inside the bin folder of VP Suite installation directory.
As always, feel free to let me know if there are any questions.
