It is WX related, problably missing EGL support in glew. 

It worked my in own tests. I realize now that was because I have this
setting in ~/.config/hugin.conf:
[GLPreviewFrame]
[...]
isShown=0

(i.e. The OpenGL Preview window does not autoopen). I then need two
klicks to actually open it (the first try fails) but apart from that
hugin works.

Does this workaround also work at your system?
