This is mostly based on victor's
earlier bug report, which wasn't very precise, but with additional information provided on IRC.
To reproduce, edit $UserData_Root/glestuser.ini and set PlayerName to
victorJ_Br. When done, start a fresh rebuild of the latest svn revision, which, to date, is r3502. Go to the 'options' menu and try to change your player name to
GGGGG. While trying to do so, MG will crash. This is on Ubuntu 12.04, x86_64.
The following output is produced:
