mail crashes
Every time I open Mail, it crashes.
MacBook Pro, OS X Mountain Lion (10.8.2)
Same problem with our late 2012 mini, which has the same configuration and OS version as the OP's. This started a few days ago, and I assumed that my HDD was in the way out. I'm a month out of warranty, but am still covered by my credit card's extended warranty protection. Hopefully it's just a software upgrade.
