Qt creator crash under Centos

[mickey]

Hello,
I have installed Qt designer and Qt creator on 'Mate', (Centos). To install Qt creator I used yum install. Everything seems fine. I create a .pro with Creator but when I save the project 'Creator' crashes. It seems to do everything right. Here the files created:

exercise1.pro
 exercise1.pro.user
 main.cpp
mainwindow.cpp
mainwindow.h
mainwindow.ui

exercise1.pro
 exercise1.pro.user
 main.cpp
mainwindow.cpp
mainwindow.h
mainwindow.ui

To copy to clipboard, switch view to plain text mode 

I also can't open the .pro: it crashes immediately. I found around that it can be a problem of compability of something about KDE4 ? Here my installation:

konsole --version
Qt: 4.8.5
KDE Development Platform: 4.14.8
Konsole: 2.10.5

BTW: I'm launching Creator from 'Mate'

Any suggestions?
EDIT: I also can't do 'Tools > Options', because it crashes!

I have the exact same problem. Running Gentoo Linux, qt-5.6.1, qt-creator-3.6.1.

Qt Creator crashes when opening a project, or when tools/options is selected.

The problem showed up when I upgraded to qt-5.6.1. Before that (with qt-5.5.1) qt-creator-3.6.1 worked fine for a couple of weeks.

I have tried a lot of things and nothing has helped yet.
