I get a repeatable segfault when clamscan 0.72 tries to scan a certain large Word file.

I wasn't sure whether it was a zsh or a clamav segfault, so I tried it from bash - still segfaults.
clamav 0.71 handles the same file just fine.
I'm running Mac OS X 10.3.4, with clamav installed via the Fink project. http://fink.sourceforge.net/
I previously reported a segfault when scanning a certain large Word file with clamscan 0.72.
I still get a segfault when using clamscan 0.73.
This file contains some embedded graphics, if that is relevant.
