I see something similar with Nvidia NVS 140M on my installed F18. Crash after unlocking the screensaver.

Proposing as Beta blocker.
Comment 2 Adam Williamson 2012-09-26 18:03:33 UTC 
Discussed at 2012-09-26 blocker review meeting: http://meetbot.fedoraproject.org/fedora-qa/2012-09-26/f18-beta-blocker-review-1.2012-09-26-16.03.log.txt . Accepted as a blocker per criterion "after firstboot is completed and on subsequent boots, a system installed according to any of the above criteria must boot to a working graphical environment without unintended user intervention." - we're not really keen to start adding criteria for every possible case of 'perfectly normal desktop operation crashes X', we decided to simply affirm that a desktop which crashes on the unlock screen is not a 'working graphical environment'.

garretraziel suggests this may be fixed with latest packages, Martin and Kamil will re-test.
Comment 3 Kamil Páral 2012-10-03 07:50:58 UTC 
Yes, this is now fixed.
