ERROR: QXcbConnection: Could not connect to display

I've installed a program and when I ran it, I have this following error:
QXcbConnection: Could not connect to display
I tried to search on the internet but didn't find something for my case.
After running the debugging I saw that the error came from this part: QApplication app(argc,argv);
I use QT_5_4_1
Can someone help me ?
Are you using XCB ?

@SGaist XCB ?
EDIT: I searched on the internet, and I don't remember to have installed that. I don't know exactly how it works also.
Then what distribution are you running ? Which Desktop Manager ?
