Using DRI snapshot from 06 June 2005. Compiled against kernel
2.6.11.4-SL93_BRANCH_20050531140557-default on SuSE Linux 9.3 Pro. Wine is
wine-20050111-0.1. X.org is running in 16 bpp.

Hardware is IBM T21 (Savage IX).

Steps to reproduce:
===================

Fire up 'wine lightwav.exe' and add some geometry. Spin a viewport and the
application will fail. From a terminal, you can see the debug information from
Wine. Also works for 'wine modeler.exe'

Crash information:
==================

a) For lightwav.exe
wine: Unhandled exception (thread 0019), starting debugger...
WineDbg starting on pid 0x18
Unhandled exception: page fault on read access to 0x00000000 in 32-bit code (0x4
