Any other ideas?

I tried it with the current master build from GitHub (source) and it also result with the same error, seems like a bug.
Here's the log:

Code:

I saw that you just made a new issue in GitHub (seconds ago) regarding this issue.
I suggest you to add a log for easier debugging, you can find it in you logs folder in your data dircetory.
