Ouch. I'm not able to reproduce this. Is it possible to provide some additional info on how to trigger the exception? Obviously, it looks as if it's related to #51, but without being able to reproduce it, it's difficult to develop a solution strategy.

OK, I'll try to debug to get more details about what's happening. Hopefully, I get to it before the holidays.

Meanwhile I've tried it with different workspaces and installations, but no luck in reproducing the problem. Don't push it too hard, since I also can't promise to deliver a fix before the holidays...

fappel commented 8 years ago

Since I couldn't reproduce the problems with the latest version and there hasn't been new information on this topic for a while I close this issue. Feel free to reopen if the problem reappears and/or there are new insights available that can help to reproduce the troublesome behavior.
