So, firstly, this is a Qt issue. It may well be that the multiwindow mode window manager for the Cygwin X server doesn't satisfy some expectation that Qt has (and I would be interested to know what that is), but Qt crashing is never the right thing to do. A backtrace of the Qt client when it crashes might be informative. > Please note it is a Qt reproducer. We have some hard coded paths in > the Makefile that you will need to modify.

I note that an Ubuntu 12.04 only seems to have Qt 4.8.1.
