[winswitch] Xpra 1.0.3 won't launch on Mac OS X El Capitan? (10.11.6)

[Stroller]

Hello,

I've just installed the latest Xpra linked on the frontpage of xpra.org and the icon just bounces in the dock a couple of times when I try to run it.

In the Console I see:

15/02/2017 16:51:49.242 WindowServer[146]: assertion failed: 15G1217: libxpc.dylib + 22551 [54D1328E-054E-3DAA-89E2-375722F9D18F]: 0x13

If I go back to the previous version (the one dated 2017-01-31, I think - md5 e87050449cf4b372680eccd0bffb7bdd) it launches fine.

Not sure if this is just me doing something stupid, but I thought you might want to know.
