mairix crashes when searching in MD5Update()

[Caspar Clemens Mierau]

Binary package hint: mairix

Hi,

I am using mairix a lot for mbox files based search. Out of a sudden mairix crashed today multiple times without any clear reason. I fetched a backtrace:

The occured when doing a simple "mairix searchstring" search. After running mairix manually ("mairix") for a reindex everything was fine.

The only thing that changed were some mail movements inside the mboxes before doing the crash search.
