Could you try running the Worker in nogui mode to try and get an Apple crash log from it?
To do that run /Applications/Thinkbox/Deadline10/bin/deadlineworker.exe -nogui. As long as there isn’t another Worker running on the machine the Worker should fire up and start working as normal. But without QT loaded (which may be the cause of the hang+crash) a log from a crash in nogui mode may get us another thread to pull on.
Thanks!
