Pyfa crashes after multiple right-clicks

[simonszu]

Hi,

i have the following issue:
Pyfa with wxWidgets on Mac OS 10.11.1. Open a ship class, the list with the several loadouts appears. Right click on one fitting. Repeat the right click, eventually Pyfa crashes.
The console output is

Nov 18 17:48:00  pyfa[29212] <Notice>: 2015-11-18 17:48:00.189 pyfa[29212:11443470] *** Assertion failure in -[wxNSMenuItem setSubmenu:], /Library/Caches/com.apple.xbs/Sources/AppKit/AppKit-1404.13/Menus.subproj/NSMenuItem.m:839
