I remember having a problem with old Creator that had to do with showing 
contents of variables. I don't remember the details though. I only 
remember that the issue was gdb. I was using a version that was not 
working correctly with Creator 2.8. I had to downgrade to an old gdb. 
7.5.1, I think.

I can't reproduce the problem anymore, since I've since switched to 
Creator 3 (now on 3.3.2.) This is rather easy to upgrade to now, as Qt5 
is now in portage (although in ~arch.) If you want to upgrade, note that 
you can still develop for Qt4 just fine. Qt5 is only used to run Creator 
itself, it doesn't have any effect on the version of Qt you want to 
develop for.
