Bug#644360: gnugk segfaulting

[Jan Willamowius]

Hi Jan,

GnuGk 2.3.2 has a number of known bugs that have been fixed in the
meantime, some of them resulting in a possible crash.

I would suggest that Debian switches to GnuGk 2.3.5.
Until then you can use the GnuGk executable from the gnugk.org
website which should run on Debian.

Regards,
Jan
