--- Comment #8 from Caolán McNamara <caolanm at redhat.com> ---
I think you've definitely found the crashing line. That appears to be the only
std::deque::push_back

pScreen is just a GdkScreen *pointer* though and nMonitors just a number so
custom classes doesn't arise, just as well be two integers really, so perhaps
the problem is with the maScreenMonitors or above in the stack trace

I can't actually see how one could get from vcl::Window::AcquireGraphics to
GtkSalSystem::countScreenMonitors

countScreenMonitors is called either from GtkSalSystem::GtkSalSystem which
should be done long before now or from screenSizeChanged and monitorsChanged
which should be called from signal callbacks which isn't the case here.

so I don't know what's going on here. I feel a more generic bug further up the
stack though.
