I have random crashes of my ubuntu (9.10 ) system (also with the previous release 9.04)
from /var/log/syslog:
Nov  3 17:09:29 ptvb-desktop kernel: [ 7933.363641] npviewer.bin[3858]: segfault at f4cb1030 ip 00000000f70a5ded sp 00000000ffe4ae94 error 4 in libpthread-2.10.1.so[f709e000+15000]

In the previous crash today, a similar message appeared but caused by 'nautilus' instead of 'npviewer.bin'
because the crashes restart my x-server each time, the bug might be related to the proprietary nvidia driver.
I use the most recent nvidia driver 185.18.36 (during the previous crashes I used the driver I installed myself by downloading from the nvidia website; during the latest crash I was using the driver provided by the ubuntu repository, installed by the restricted driver manager)

after the previous crash (caused by nautilus) and restart of X, I was even logged in as 'root' instead of the normal user account I was using before the crash.
