Bug#507845: Unwell configured Locales can be the reason?

[Maelvon HAWK <maelvon.hawk@laposte.net>]

I'm try to figure out if the modification of the locales can be the 
origin to thoses freezes. I've put the locales to fr_FR.UTF-8, just 
after a fresh install on a Ubuntu 9.04, and that after that, the freezes 
appears!

The libc6 is hightly connected to the locales, no?

I've read the libc6 contains the locales, can't it be a mal configured 
locales variables?

As I'm a french user, seems that some others are french, and in my case 
I've modified the locales to "fr_FR.UTF-8", just after the first install 
on Debian, perhaps that's that who put the mess in the box (Debian or 
Ubuntu).

I'm trying this trail on fresh install.
