Hi guys, yesterday I made an upgrade to 13.04 from 12.10, I got a problem today with Compiz and libunityshell.so, so I removed (and purge) almost all applications (compiz, unity and beyond... firefox, chrome, libreoffice, lightdm)...
After that I reinstalled all the applications (ubuntu-desktop) and now it is working fine everything (BTW Ubuntu 13.04 is really fast )
But now I have a problem with some apps (qt apps) like qbittorrent, VirtualBox, etc. All of them looks weird and with KDE icons... When I installed all this applications they just works using the GTK theme, but now they looks ugly.
Do you know how can I recover this aspect? I already tried using qtconfig-qt4 (as normal user and as sudo) but that didn't work.
Attached is an image from one dialog window in qBittorrent.
