The jUnit example reveals the same problems: Blank window, killall -9 is the only way to terminate.

Do you know if this problem is related to Ubuntu driver issues or something similar?

Not sure what it's related to yet, but if you capture that debug output to a log file, and attach it to a Bugzilla report, it'll definitely help make sure this gets fixed. I just noticed some freezing in the process of working on another unrelated bug, so I haven't been able to really look into it.
