bitcoin-qt.exe keeps crashing

[tonto]

I'm on version 0.6.0.6-beta, Win7
 
I launch it and after a couple minutes it crashes.
 
In the client window is the error message:
EXCEPTION:22DbRunRecoveryException
DbEnv::txn_checkpoint: DB_RUNRECOVERY: Fatal error, run database recovery
C:\Program Files(x86)\Bitcoin\bitcoin-qt.exe in ThreadDumpAddress()
 
Another window pops up:
 Microsoft Visual C++ Runtime Library
 
It complains that the app is crashing.

I reinstalled to 6.0.6, not quite sure what version I had before that.

ugh, never mind. I feel like such a n00b.
 
I replaced my Bitcoin folder (in my AppData) with a backup, and it runs fine.  So there was a corrupt file in there somewhere.
 
Bleh.  So lesson learned for anyone reading along.  keep backups and try that first.
