[Interest] Qt 4.8 qtcreator

[Szalata, Zenon M.]

I did some more testing and I seem to have the same problem on a number of RedHat Linux computers.
The problem is:
starting qtcreator is unsuccessful, it crashes with a core dump after printing the
QPixmap::handle(): Pixmap is not an X11 class pixmap
messages.
I just installed qt 4.8 (SDK) and am using qtcreator that came with the SDK.  It is a 64bit version,  I get the same problem on a 32bit Linux where I installed the 32bit version of the 4.8 SDK.

Here is  back trace:

Any help will be greatly appreciated (I am kind of stuck; not sure what to try next).
Thanks,

I am having more problems with the qt 4.8 installation on RedHat rhel6 Linux.
I invoke the QtCreator/bin/qtcreator and it crashes after printing these messages:

zms at esaanal2 $ qtcreator&
[1] 22105
zms at esaanal2 $ QPixmap::handle(): Pixmap is not an X11 class pixmap
QPixmap::handle(): Pixmap is not an X11 class pixmap
QPixmap::handle(): Pixmap is not an X11 class pixmap
QPixmap::handle(): Pixmap is not an X11 class pixmap
QPixmap::handle(): Pixmap is not an X11 class pixmap
QPixmap::handle(): Pixmap is not an X11 class pixmap
QPixmap::handle(): Pixmap is not an X11 class pixmap

[1]+  Segmentation fault      (core dumped) qtcreator

When the installation finished I was given a choice to start qtcreator and at that time it worked fine.  When I start it from a command line it crashes.  How am I suppose to start it?

I see the same problem on 64bit and on a 32bit computer.  I ran the 64bit installer on the 64bit machine and the 32bit installer on the 32bit machine.

Thank in advance,
Zen
