[Kwintv] reproducible crash with qtvision

[Rizsanyi Zsolt]

Hi!

I have found a reproducible crash with qtvision. :(

Steps to reproduce:
Open configure window, press Cancel. And now try to change channel...

And you get the next backtrace:

I have not looked into this yet, but I will in the next few days, when I have
