Unsolved QTCreator 5.4.1 startup Segmentation Fault

Hi,
I'm new.
I have a problem with XUbuntu and QtCreator.
when I try to startup qtCreator by script qtcreator.sh in Qt5.4.1/Tools/QtCreator/bin/ I receive this message:QFactoryLoader::QFactoryLoader() checking directory path "/home/pluservice/Qt5.4.1/Tools/QtCreator/bin/plugins/platforms" ...

Hi, just guessing but you try starting Qt Creator without the Welcome plugin, type this in Terminal:
./qtcreator.sh -noload Welcome
-

./qtcreator.sh -noload Welcome
thanks for reply.
but It doesn't resolve the problem -
Ok, maybe time for some diagnostics to see where the problem is:
strace ./qtcreator.sh

Interesting is usually what is at the end where the application crashes.

Hi just guessing (again!) but when googling, some people recommend typing this in Terminal:
sudo apt-get install libx11-xcb1
-

Ok
I try it but nothing.
for a moment qtCreator started but after crash and the problem come back. -
Hmmm, maybe try upgrading to Qt 5.5.1.
