$ dpkg -l *glx*
ii  libgl1-mesa-glx 7.6-1...

but that's all just a red herring.

Most likely you're not using a tiling window manager, so
panoramaChanged doesn't get called at the same point. [This particular
segfault has nothing to do with openGL.] The reason it segfaults is
pretty simple; m_parent is NULL, and DoSetSize in libwx dereferences
the null pointer. It's most likely a bug in hugin somewhere that
results in m_parent being NULL.
