Bug#550183: Breaks Default button in some eclipse dialogs (and rcp apps)

[Simon Pepping]

The same happens to my eclipse. There is also a bug report in eclipse:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=291257. Citing: 'GTK
2.18 introduced a new way to interact with GdkWindows. This is what
introduced the problems that you are seeing and why exporting
GDK_NATIVE_WINDOWS fixes it (they added that flag to allow us to
revert to the old behavior). It is not the final solution, we need to
see what is broken and either fix it or have GTK fix it in the next
2.18.x release.' Workaround: export GDK_NATIVE_WINDOWS=true.

This means that GTK2.18 is backwards incompatible and breaks existing
applications. The upgrade must warn users and a way must be found to
minimize the effect of this upgrade.
