Not really. It's obviously triggered by the screensaver. The machine
runs SuSE's default: gnome-screensaver with mode =3D random and a list
of 189 candidate screensavers, so I can't tell which one(s) of those
actually triggers the problem.

But perhaps that doesn't matter anyway. I recently collected another
X backtrace with kernel 2.6.25-rc7 which looks quite different in
the libglx section:

0: /usr/bin/X(xf86SigHandler+0x81) [0x80e6d81]
1: [0xb7ef7400]
2: /usr/lib/xorg/modules//extensions/libglx.so [0xb7b7d8e8]
3: /usr/lib/xorg/modules//extensions/libglx.so(DoRender+0xdd) [0xb7b7645d=
]
4: /usr/lib/xorg/modules//extensions/libglx.so [0xb7b7657c]
5: /usr/lib/xorg/modules//extensions/libglx.so [0xb7b7aa6d]
6: /usr/bin/X [0x815809e]
7: /usr/bin/X(Dispatch+0x1af) [0x808f68f]
8: /usr/bin/X(main+0x47e) [0x807717e]
9: /lib/libc.so.6(__libc_start_main+0xe0) [0xb7c8bfe0]
10: /usr/bin/X(FontFileCompleteXLFD+0x1e5) [0x8076501]

But I know next to nothing about GL, so I'm out of my depth there.
I'd welcome any suggestions on how to provoke the crash more
regularly so that I could attempt to bisect.

Thanks,
Tilman
