Generated Python script prevents blender from rendering, hangs instead
I'm using Arch Linux fully up to date, OpenJDK 15.0.2 (also tried 1.8.0 and 11.0.10), Sheepit client 6.20364.0, and no matter how long I leave it it always hangs on "Preparing scene 0%" on the "Can Blender be launched?" project.
It appears to be running blender as rend.exe however the process sits there doing nothing. I have tried clearing the cache file which makes no difference. It occurs whether I select CPU or GPU rendering.
I've noticed that running the command in the sheepit debug output without the -P /tmp/farm_##/script_## option immediately renders the file.
If I render the file and put it in the correct place (i.e. run blend.exe without the Python script), then SIGHUP rend.exe, the client continues to then try the machine strength test but fails with the same problem.
