Something about wrapping the code that would normally be used; the vesa driver may cause it on that machine, too.

Please attach your X server log file (/var/log/Xorg.*.log) to the bug report as individual uncompressed file attachment using the bugzilla file attachment link below. We will review this issue again once you've had a chance to attach this information. Thanks in advance.
FYI, it does also happen with mga as the Device; vesa was just testing that ajax did. Will attach log file soon.
Created attachment 310825 [details] Xorg log, having reproduced the error This does seem to require the 1400x1050 resolution; it did not happen at 1600x1200 when I was trying to give a logfile in which it had been reproduced.
Looks more like server to me -- crash in usr/bin/Xorg(ValidatePicture+0x11) [0x81478e1]
URL doesn't open. Please, could you confirm if this URL causes the same crash? http://en.wikipedia.org/wiki/Special:Allmessages I'm having similar crashes in Fedora 8 with the above URL, with intel (open-source) and nvidia (closed-source) drivers, but with a different backtrace: Program received signal SIGSEGV, Segmentation fault. 0x0044817f in fbRasterizeEdges (buf=0x8695098, bpp=8, width=436, stride=109, l=0xbffaff54, r=0xbffaff2c, t=-2147481464, b=28571510) at fbedge.c:171 171 ap[lxi] = clip255 (ap[lxi] + N_X_FRAC(8) - lxs); (gdb) backtrace #0 0x0044817f in fbRasterizeEdges (buf=0x8695098, bpp=8, width=436, stride=109, l=0xbffaff54, r=0xbffaff2c, t=-2147481464, b=28571510) at fbedge.c:171 #1 0x00440a0f in fbRasterizeTrapezoid (pPicture=0x85fe368, trap=0x864e978, x_off=<value optimized out>, y_off=0) at fbtrap.c:143 #2 0x0035534a in _nv000753X () from /usr/lib/xorg/modules/drivers//nvidia_drv.so Also bug 448586 seems related.

FWIW, the URL in comment #5 does also cause a crash, although I'm not sure that it's the same problem. Attaching log from that crash.
