The attached patches fix the issue in GTK+2 and prevent crashing of m-d-p. Since this issue caused much inconvenience for users, the fix should be backported to all current stable releases of Ubuntu. [Test Case] The easiest way to reproduce it is via Virtualbox: 1. Run mate-display-properties in the VM. 2. Make the VM go full-screen. 3. See m-d-p crash. [Regression Potential] After several months of testing the patched version of GTK+2 in Debian Jessie, I found no regressions. I consider the regression risk very low here. There were originally some bugs with a few applications (notably Spotify) crashing. We think we've backported patches to fix that - some refcounting issues - but please check a few apps to see they still work.
