When I run X using startx, with the latest version of Helix Gnome (as of 17
Aug 00), and I view the jakarta-ant_README file X crashes.  

The exact procedure is as follows:
1) startx
2) Open gnome-terminal
3) do a more jakarta_ant-README file
4) on the second viewed page X dies

My hardware: 
ATI Rage 128 Fury
AMD K6-2 350 Mhz

This is reproduceable.

I did the following tests and it continued to happen.
startx -- -bpp 16
startx -- -bpp 32

I tried using the X86_SVGA version from XFree86.org and it happens.

When I turn on no_accel in XF86Config it does not happen.

When I run startx I have done the following line:
startx 2>&1 | tee logfile

All of these log files and the jakarta-ant_README file are avaliable for
testing if you wish to have them.
