--- Comment #16 from Michael Schwendt <bugs.michael@xxxxxxx>  2008-09-01 06:55:52 EDT ---
It's a warning about a potential buffer overflow, that ought
to be examined by the package maintainer. The warning alone
is reason enough to say "Ooops, we don't want to release this".

I've reported above bug to upstream via email.

Insecure C string operations like that lead to vulnerabilities.
There are more in the code. No matter how likely it is to trigger
them, they ought to be fixed.
