Qprocess...hanging entire application!!!!

[nupul]

I have a few buttons which when clicked, execute the following type of commands

kfmclient openURL media:/hda1/

kfmclient exec Firefox.desktop

etc

Now the funny thing is that everything was working fine till yesterday and today !!!!!!!!!

i.e the QProcess executes - i can use it normally, but my app at the back gets hung up! i have attached the snapshot of my app top right corner....the base colors of the windows/groupboxes etc are being displayed....also if i move the window (the one launched via QProcess) around, it just erases the contents of my app!!

What do you think is wrong!

Thanks

ps: i tried doing startDetached(process_name), I also have waitForFinished(-1) enabled....but it seems the launched process never 'finishes' and thus control never returns back to my program!!!

EDIT: when i run "ps -e" to see the issue i get this mentioned

PID TTY 00:00:00 kfmclient <defunct>

any relation?
