There is a problem occuring when receivefragments is called:

It doesn't happen all the time, probably an off by 1 error. On line 183 sometimes the message returned is null which causes all the errors above to be spieled.

I'll try to recreate it. Did this only happen with running the test suite?

It happens occasionally, seems pretty random, but only when you have at least one GUI running and then try to run the test suite.
