One small change in the destructor:

HTMLCachedImage::~HTMLCachedImage( )
{
    if (pixmap) delete pixmap;
    pixmap = 0;
}

should be 

HTMLCachedImage::~HTMLCachedImage( )
{
    delete pixmap;
}

delete tests for the pointer being 0, and it does not make sense to assign
a variable in an object 2 milliseconds away from being deleted :-)

Wether your patch works I can't say, since I haven't tested it.
