Hello List,

We just migrated from a PPC Xserve to an Intel Xserve.

I used "rsync" to bring everyone's home directories over, and in the
back of my mind wondered about how it would handle the binary index
files... only one way to find out! :)

Once I tried to login to IMAP, I got the following results:

Naturally, deleting everyone's ".imap" folders fixed the problem.

I'll attach the crash report to this e-mail. Hope this is useful to
someone on this list!

Best, Cabel Panic
