"Pixmap is not an X11 class pixmap" warning

Hi,
I downloaded new Qt Creator sources today 26-Sep from current master, I used Qt 4.7.4, gcc 4.4.2 and RedHat4 based Linux. Building Qt Creator was successful without issues. However, now when I launch Qt Creator, I get these errors:

harju@trx 2.3.81-32bit-NOEL4/bin % ./qtcreator
QPixmap::handle(): Pixmap is not an X11 class pixmap
QPixmap::handle(): Pixmap is not an X11 class pixmap

Qt Creator people don't want to fix this because this is "not Qt Creator issue"
