#420012 bug in libmrss or in glibc?

http://bugs.debian.org/420012 is currently twisting my head.

http://people.debian.org/~nion/nb-bt-full-complete.txt shows
that this is no bug in the newsbeuter package. I don't 
really understand why the encoding variable is out of bounds 
and didn't find out with a quick look into libmrss code.

What makes me wonder is that a recompile solves the issue.
The bug doesn't appear with version 2.3.6... of glibc but 
with the new version in unstable 2.5.

If the recompile solves the issue I am curious how this is 
a bug in libmrss or newsbeuter since the mrss version didn't 

Is it possible that it's a bug in libc?
Any help is appreciated since I don't know how to do further 
debugging here.

To reproduce this bug install newsbeuter (with 2.3.6.ds1-13 
of libc6 installed), echo 
start newsbeuter, press R to reload. This will work without 
any problem. Then update to 2.5-3 of libc6, start 
newsbeuter, press R and see it crashing :)

Kind regards
