Hi Christian,
I believe all of these issues are caused by the same bug and should be fixed in the next release.
We're in the process of packaging and testing it right now so we should be able to release it in the next couple of hours.
I'd suggest you try upgrading to the new release, and re-attach the evidence and I believe it will start working.
Sorry that this is causing you problems, if the problem isn't fixed by the next release I'll follow it up straight away.
Simon
