I can confirm this with Ubuntu Intrepid, though I don't have the problem
in my jhbuild environment (built from svn).

I don't have this problem in other gtkmm-based application, such as
Glom, in Ubuntu Intrepid.

I guess we need to try
a) Breaking down that example to see if something there is causing it.
b) Trying the same thing in a C example.

Maybe then we will identify what Ubuntu needs to update/patch to fix it.
