Qt- Creator fails in SUSE and Fedora

[ArcNexus]

Hi All

I Have a problem with Qt-creator in openSUSE 12.2 and also in Fedora 17.

When I open my project and open a UI. Qt-Creator 2.5 and Qt-Creator 2.6 fails and exit without a message. After several failed attempts, mysteriously it works perfectly.

It work perfectly in Ubuntu 12.10 but not in OpenSuse or Fedora. I have tested in 3 machines :-(

Any idea?

Thanks, and sorry for my english.

I Have tested in other desktops and it only fails in KDE 4.8 and KDE 4.9.
works fine in Gnome3, lxde xfce....

This sounds a bit like Qt Creator picks up some KDE plugins (e.g. for image formats, or designer) which are linked to an incompatible version of Qt.

Now I have Debian SID in my computer. And Qt-creator works perfect in Debian with KDE 4.8.

Thanks for your answer.
