Iceweasel not starting

["elijah rutschman" <elijahr@gmail.com>]

Hi all,
I recently installed Debian Lenny onto an EeePC 701. I installed
"firefox" with apt-get, which I believe is just a wrapper for
installing iceweasel.
However, if I try to launch either "iceweasel" or "firefox" from an
xterm, nothing happens, and there is no helpful console output.

$ iceweasel
$
<no new window>

$ firefox
$
<no new window>

I have tried purging iceweasel and firefox with aptitude, then
reinstalling, to no avail.  Any help would be appreciated.

Thanks,
Elijah Rutschman
