Mysterious crash on multiple virtual machines

[soulweaver91]

(Split off of #27.)

PC crashes on a Vista x64 VM right after starting up. The crash occurs while trying to set shader parameters, which is odd, because it gets past the initial GPU checks just fine (reports as shaders available and same maximum texture size as in the host OS itself) and apparently the shaders themselves also load properly as they didn't trip up the temporary asserts either.

Lines 494 to 496 of CarrotQt5.cpp at the time were as follows:

494:            windowCanvas->draw(loadingScreenSprite);
495:            BitmapString::drawString(getCanvas(), getFont(), levelName, 400, 360, FONT_ALIGN_CENTER);
496:            windowCanvas->updateContents();

It is a mystery as to why the execution even is in the loadLevel function in the first place, as the game should be entering the menu, not a level, as no filename was sent as a command line parameter.

Also occurs on Windows 7 x64, leading to believe this is a problem with VMware rather than the used version of WIndows.
