I had this problem on MP1.1.3 as well. The only way I got rid of the problem was to uninstall the following Windows updates.
KB2533623, KB2507938, KB2567680
I have confirmed this to be the problem on my system because if I reinstall the updates the crashing starts again. I had two clients running win7 32bit with the same problem and same fix.
I also tried the updates again after upgrading MP to 1.2.1 thinking the problem may have gone away but it hadn't.
I am not sure the relationship between the three updates. If I uninstall each update individually the problem remains but if I uninstall all three the problem is gone.
Curious to see if this fixes your problem as well.
If someone is looking into it can they look at the other two KBs I listed as well because for me it didn't matter which one of the three I had installed they all caused the same problem.
AW: MP 1.2.1 crashes on resume from standby / hibernate.
