Yes, Qt bots run on Ubuntu 12.04. It's super easy to setup a QtWebKit build
environment on Ubuntu,just follow the "First steps before gardening" here:
http://trac.webkit.org/wiki/QtWebKitGardening

Meta packages install all dependency, build-qt5.sh build the necessary
Qt version from git. It doesn't take more than an hour.

Thanks for looking into this bug.
