Sound's like you're just being obstinate, then. It works, just not how you would prefer (well, I would also prefer that it didn't give an error screen like that, but that's besides the point). This is still early days of an open source project, and for that one should have a bit more understanding than for corporate products. A lot of other services also started out very unpolished and took time to get better.
The good thing is that you should be able to contribute and make it so that it doesn't do that since you wrote you were a software developer for your whole career.

Who said I can program?
EDIT: If I could do the work to make it work better I would.
