segfault error 6, and trap divide error

[LimCore]

Xgl (with gnome, on vidia 8600 gt on nvidia's binary drivers)
crashes quite often when doing different stuff.

Also sometimes programs seem to crash because of X problem (but usually the entire X server crashed and restarted)

dmesg:

[177652.594238] Xgl[10852] trap divide error rip:43bec0 rsp:7fffc35219e0 error:0
[182625.181313] Xgl[2461] trap divide error rip:43bec0 rsp:7fffa6dfa2c0 error:0

(and lots of simmilar)

All happend with firefox open - ironically to ubuntu page "http://ubuntuguide.org/wiki/Ubuntu:Gutsy#What_to_do_if_Ubuntu_freezes"

Just happened today for first time, 3 times in a row. Seems OK since starting to post this. I keep saving the msg in a file though.

Also noticed my clock panel applet time is frozen at 3:37:46 - pic attached in case any relationship.

Similar problem here, only happens occasionally, started today (haven't added any software / done any updates recently).

X crashes completely, screen blacks out, have to login again. Happens when I access some rather large dev. page (can't show it) in FireFox 3.0 (Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9) Gecko/2008061017 Firefox/3.0), but also consistently on the page mentioned in the post above this one:
"http://ubuntuguide.org/wiki/Ubuntu:Gutsy#What_to_do_if_Ubuntu_freezes"

Relevant bit from /var/log/syslog:

xserver-xgl has been deprecated upstream, and removed from Intrepid. Closing the bug as won't fix.
