"buffer overflow" error

[kakashizilla]

Hello,

I have compiled icecat 3.0.7-g1, installed it in my home directory and 
everything works.
Then I have decided to build the rpm to install it on my system, and here is 
the bug : 
 - when I run the binary "icecat-bin" directly, no problem ;
 - when I use the launch script "icecat", there is a buffer overflow, with the 
message

I know that a similar bug was fixed for .deb package 
<http://lists.gnu.org/archive/html/bug-gnuzilla/2009-03/msg00015.html>

Does someone know what is the origin of the problem and how to fix it ?
Otherwise do you think it is a good idea to run directly the binary "icecat-
bin" ?
Thanks a lot !
