Hi No!No!No!Yes!
I had another crash today with all my desktop widgets disappearing after locking device.
Coincidentally I had setup syslog just in the morning today
Attached is the log with unnecessary parts (according to me) removed,except those between device lock and unlock.
I have highlighted the device lock events in bold.
What I think are the cause/result of crash are in red.
Glib also complained of some critical errors don't know if its related.
Unfortunately I do not know which process had pid 1335 so from now now on I am writing process list to file before/after device lock.
Now to wait for another crash

EDIT: 1335 was hildon-home as well
