Bug Description

Ubuntu 14.04.2 LTS
unity-gtk2-module:
  Installed: 0.0.0+14.04.20141212-0ubuntu1

1. Download Eclipse 4.4.2 available here:
https://www.eclipse.org/downloads/download.php?file=/technology/epp/downloads/release/luna/SR2/eclipse-java-luna-SR2-linux-gtk-x86_64.tar.gz
2. Start Eclipse. Close the Welcome screen.
3. Mouse over to "Window" menu on top bar, click, move mouse down to "New Window", click to open a new, empty window.
4. Mouse over to "Window" menu on top bar, click. Crash occurs.

If Eclipse is started with UBUNTU_MENUPROXY=0, it doesn't crash.

I can confirm this bug. Same setup, also UBUNTU_MENUPROXY=0 prevents the crash.

Note that https://bugs.eclipse.org/bugs/show_bug.cgi?id=461311 has a short SWT-only code snippet that demonstrates the bug without the need to load all of Eclipse.

The steps to reproduce this using Eclipse are now more complicated since Eclipse has a workaround that disables the feature was adding a radio buttons to the Window menu when running under Ubuntu. You can still reproduce it with Eclipse by selecting Run -> Breakpoint Types. The Window menu no longer causes the crash.

This bug is fixed in Ubuntu >= 14.10 but a lot of people use 14.04 LTS. It would be very appreciated to get this fix backported to 14.04. I am attaching a simple patch that backports the fix to 14.04. Please let me know what I can go to help further in applying this fix. I can also create a Bazar branch if that it valuable. Thank you!
