Turns out that my similar problem (SIGSEGV in libpthread on startup of JOGL app) were caused by me not calling GLProfile.initSingleton() soon enough in my app.

This is probably not exactly the same as your problem, since it sounds like you're using JOGL 1.1.1a, not JOGL 2.0 beta. But there might be some similar workarounds -- perhaps calling XInitThreads() manually in your app would fix it.
