Here is a suggestion:

Instead of using pfu functions to open your own GLX window, create a
pfPipeWindow of type PFPWIN_TYPE_X. Then call pfuInitInput(pwin, PFUINPUT_X) on
this pipe window. Then you should be able to call pfuGetEvents without
problems. This works very well for me and has never crashed using Performer 2.0
and 2.0.2.
