User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.8) Gecko/20050517 Firefox/1.0.4 (Debian package 1.0.4-2)
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.8) Gecko/20050517 Firefox/1.0.4 (Debian package 1.0.4-2)

When I try to open the above URL, Firefox says:

You have chosen to open
  tst-ieee754.c
which is a: C file
from: http://www.vinc17.org
What should Firefox do with this file?
  * Open with [less (default)]
  * Save to Disk
  [ ] Do this automatically...
[Cancel] [OK]

If I click on OK, Firefox starts less (without a terminal) and completely hangs.
I need to kill it and remove the lock manually.

Reproducible: Always

Steps to Reproduce:
1. Open the above URL.
2. Click on OK.
Actual Results:
Firefox hangs.

Expected Results:
Firefox should not hang. I don't know why it asked for less (possibly a Debian
default), but if it can start less in a terminal, this would be OK for me. See
also bug 57342.

System: Debian unstable.
