SOLVED-kdenlive gon all black after changing my gtk theme in lxapearance

I am on a Debain based distro (Crunchbang) and use GTK themes - After I installed Kdenlive it looked fine but recently I changed my GTK theme in Lx-apearance panel now Kdenlive looks all black and horrible and I tired changing to another GTK theme and also changing back to the one I was orgiinaly using but it doesn't help - Any advice?
I understand that kdenlive uses kde themes but where does it get them on my system?
here is what kdenlive looks like

EDIT
All is fine now from lxpanel I choose Preferences-QT 4 settings
and changed the theme and background colour there.
