Comment 9 for bug 799990

I've had another look at the call stack and I may have found the cause of the Qt problem: qgenericbearer4.dll is not part of the OpenLP build and therefore loaded from "C:\Qt\4.7.1\plugins\bearer\" (my Visual Studio 2010 build).
I don't really understand how, since it's not actually in the PATH, but the call stack shows that QtCore4.dll uses msvcr90.dll (and is therefore likely to be the one from the OpenLP folder) and only qgenericbearer4.dll calls into msvcr100.dll. Here's the full stack: http://pastebin.com/4csYfRc8
