Comment 1 for bug 799990

Hmm, I suspect very few people are going to have Visual Studio 2010 built Qt libraries sitting in their path on their Church presentation laptops!

I don't have Visual Studio 2010, and have no plans to build Qt myself. We use PyInstaller to package up the exe, but I'm not sure I'd even know where to begin to look at how to resolve this problem. It would likely take a long time to investigate and that time might be better used elsewhere, and even then there is no guarantee we could fix it.
However please feel free to investigate the problem yourself, since it looks like you are in the best position to do so! :)
