I'm having an issue with constant crashes when using armory to watch my offline wallet.  Once 'Scanning Transaction History' completes, armory stop responding and can only be force close.
I'm using Ubuntu for "cold storage" and Windows 7 for watching.  I've been having this issue for about 2 weeks and I've tried.
1. deleting everything in %appdata%/roaming/bitcoin
2. uninstalled armory
3. launched bitcoin-qt and let it get caught back. closed it.
4. reinstalled armory
5. launched armory and let it get synced up
At this point, I note that everything is fine.  Armory starts up fine, bitcoin qt start fine
6. Import wallet the I created using "watching only copy"
Armory Scans Transaction history.  Then crashes.  

Any idea as to how I can fix or debug this.

Edit: I'm using 0.90-beta
