Compressor 3.5.3 won't run in Lion for me

Longtime Compressor/qmaster user here.

I just upgraded to Lion, and amongst the many problems I have with Lion, the most annoying is that I cannot get qmaster to work. It appears to be working as normal:

• Cluster shows up in Compressor Submit options
• Cluster shows up in Batch Monitor
• Status menu looks the way it should
• I can successfully mount the cluster storage

When I send a Compressor job to the cluster, it shows in Batch Monitor, but just hangs after that saying "Processing"

Sending same job to "This Computer" works fine

I have tried

• Repaired privileges
• Repeatedly restarting/resetting services followed by system restarts
• Reinstalling Compressor/qmaster

Here's some Console messages
