I'm having the same issue with v0.8.5-beta, specs at bottom of the post for reference.
This happens
any time I close and then reopen Bitcoin-Qt. I was having an issue with another application last night, so I manually closed it and all other applications (including Qt) and rebooted. Sure enough, when I reopened Qt, it prompted me to re-index (which takes several overnight sessions with my processor pinned near 100%). My entire system is backed up, so this time I closed Qt and restored the .../Application Support/Bitcoin/ directory, and then re-opened Qt and received a
different error that I stupidly closed because I was so pissed. Instead I RErestored back to the unindexed version that existed and just let the reindex start. Again.
Is there some issue that prevents the data directory from being restored from backup?
