Eeli,

I got a crash that looks like it is related to the install thread. The 
call stack does not have any BT functions involved,
but it looks like a QMutex is being used after it was deleted.

Call Stack
QtCored4.dll!QMutex::lock()  Line 152 + 0x3 bytes    C++        // crash 
here
QtCored4.dll!QThreadPrivate::finish(void * arg=0x01f9a2c8, bool 
lockAnyway=true)  Line 320    C++
QtCored4.dll!QThreadPrivate::start(void * arg=0x01f9a2c8)  Line 309 +

void QMutex::lock()
{
    Qt::HANDLE self;

    if (d->recursive) {       // crashed on this line. It looks like the
                              // "this" pointer is not valid.
