blank window form with qtcreator package

[Waitman Gobble]

Hi,

I am having an issue with qtcreator (using pkg_add) from http://ftp.freebsd.org/pub/FreeBSD/ports/amd64/packages/Latest/
running FreeBSD 10.0-CURRENT amd64/SMP

When I start qtcreator a grey window form appears which is totally blank. Note that the other Qt apps appear to function (ie, qtdesigner).

On another machine running FreeBSD 10.0-CURRENT i386 (32bit) with the corresponding Qt packages installed, qtcreator runs as expected.

Pointers for troubleshooting appreciated!

Thanks,
