[racket-dev] Unlucky with Racket 6.0 (1/2)

Hello,

I have downloaded the Ubuntu precise script, installed it on a Kubuntu 
precise machine and ran it. Everything went smoothly.

If I try to run DrRacket it starts, when I go to Preferences it SEGFAULTS.

To obtain more information I go to drracket script and try to execute it 
under bash -x:
$ bash -x local-install/racket-6.0/bin/drracket
+

So, I decide to run the gracket command under gdb but now it segfaults 
immediately without displaying drracket window.
$ gdb --args /home/pmatos/local-install/racket-6.0/bin/../lib/gracket -N

I don't know enough about racket to understand what's going on. Let me 
know if you need more information to understand this.
