QtCreator 3.3.x crashes during startup with Qt5.4.1 on armv7h

I'm running ARCH Linux on my raspberry Pi2 (armv7h architecture) and I'm using the Qt binaries from the ARCH ARM repository. With Qt5.4.0, QtCreator 3.3.0 and 3.3.1 runs fine (QtCreator is also a binary from the ARCH repo).

Now, Qt5.4.1 is in the Arch ARM repo, but with that version QtCreator crashes on startup with:

[nexus@alarmpi ~]$ qtcreator
libEGL warning: DRI2: failed to authenticate
iconTheme "oxygen"
OpenGL ES 3.0 entry points not found
/usr/bin/qtcreator: line 2:   654 Aborted    (core dumped) QT_LOGGING_TO_CONSOLE=1 qtcreator-bin $@

When I downgrade my Qt installation from Qt5.4.1 to Qt5.4.0, QtCreator 3.3.x runs fine again, the OpenGL ES 3.0 entry point message does not occur.

Due to a hint in the Qt forum, I've disabled the Welcome Plugin in QtCreator, now QtCreator starts with Qt5.4.1 without problems.

There seems to be a regression in Qt5.4.1 or a bug in QtCreator. In the meantime QtCreator 3.3.2 is released and available in the ARCH ARM repo, but with the same problem, the Welcome Plugin must be disabled.
