I recently tried to compile Daniel Holbert's SMIL patches in mozilla-central. While doing this, I observed the "configure" was core dumping. The folks in the #developers channel over on irc.mozilla.org were able to help me out and trace it down to the fact that Ubuntu's dash was crashing. I worked around this by changing Mozilla's configure script to use #!/bin/bash instead of #!/bin/sh.

Apparently this crash has been fixed on Ubuntu 8.10 because Daniel himself hasn't witnessed this crash?
