Subject: octave 2.0.5 on Linux segfaults in connection with help

Bug report for Octave 2.0.5 configured for i586-pc-linux-gnu

Description:
-----------

I have several times gotten Octave to crash with built-in help.

Repeat-By:
---------

Easiest way was
help
q (which gives a warning about broken pipe to pager -- fine with me)
help (which segfaults)

Fix:
---

No idea.
