Hello,

I don't know if it can help. I had this problem on Debian wheezy with
freenx :

- problem with gtk application : texts were changed by blank.

The first solution : -norender option

The problem was linked with libcairo2 version.

So i downgrade using the squeeze version and i haven't this problem even if
the -norender option is not set.

Sincerely,

Jean
