System Information
OS: Ubuntu Server - Linux version 4.4.0-47-generic (buildd@lcy01-03) (gcc version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.2)
Hardware: Intel NUC with Core i5 (nuc6i5syh)
Graphics card: onboard (not really relevant since i try to bake)
RAM: 8 GB

Blender Version
Broken: 2.78a official and 2.78-3a9c490-linux-glibc219-x86_64 nightly

Short description of error
Set up Master and Slave on the system and ran it via console using
./blender -b /home/toxic/slave.blend --addons netrender -a -noaudio -nojoystick
respective
./blender -b /home/toxic/master.blend --addons netrender -a -noaudio -nojoystick

Master starts fine and slave is also connected. Once i send a bake job from my Windows Client to the master, errors occour in the log and nothing is baked.

On master:

Update: issue only happens if the "priority"-options in the master webUI are enabled. Unchecking the first two checkboxes avoid the mentioned error.

Seems not to be a direct regression.
As the netrender is currently unmaintained, will be removed in 2.8 and can be worked around, closing this.
In 2.8 this will be replaced with better options.

Hi Joey, can you elaborate on "better options" Im working on a network rendering addon for blender at the moment, would be nice to know what the plans are regarding this feature.
