[Qt-creator] Slow debugging with Qt Creator

[Matthias Ettrich]

Maximilien,

not that it helps much, but I'm using the same gdb 6.8-debian on ubuntu and 
getOpenFileName (on Gnome, showing the native gnome file dialog) works very 
fast running inside gdb in creator.

We too are interested in what the problem could be.
