I did not test the relevant patch, since I don't know how to compile Xorg. I could try using the xorg-edgers ppa to confirm, if that would be ok.

It seems that Xorg crashes whenever an arc is drawn. I talked to the main dev of Zyn and he said that its a Xorg bug. I also turned off the knob drawing procedure in the source and the crashes stopped. This is a relevant patch: http://marc.info/?l=freedesktop-xorg- devel&m=142850468414906&w=3 When I open Zyn, my screen turns black and around 20 seconds later my login screen shows up. I hope you can fix this problem.
