It affected me in 2 situations (i guess, is same bug ...):
When i open dash and type in to find a file on my hdd. But bug not immediately starts, there are about 5 - 10 seconds waiting.
When i try the search a 2nd time, it works. When i try another search about 1 hour later => bug again.

And i have now also problems to force my dell-notebook to go in standby. Screen becomes black for 1 or 2 seconds, network-connections stops, after that, desktop is here without changes again and network-connection is up again.
But no standbye ....
