242,DSI crash closing YAM when connection is disabled,samo79,,"I found a strange bug in latest nightly build (20-12-2010), YAM will crash in certain situation when internet connection is turned off

How to reproduce it:

- Disable internet as you like
- Open YAM
- Start the search for updates option (obviously YAM tell you that this operation it's not usefull without an internet connection)
- Close YAM normally

After you close it, YAM generate a DSI crash, here my GR log:
