gdb with Qt

Hi,

I currently try to debug a Qt application with gdb. I adapted the setup from `ports/run/gdb_monitor_interactive.run?` and tried it with the framebuffer test and tetrix. The framebuffer test worked fine but with tetrix it hangs after the first continue and doesn't seem to break at `binary_ready_hook_for_gdb`. There's also no further output in Genode so I suspect that nothing is executed anymore. This seems only to happen with Qt applications.

Did anyone had a similar problem?
