gimp's mouse clicks don't work on pegged menus

[Rocko]

Binary package hint: gimp

gimp's 'pegged' menus recently stopped working (see attached screenshot).

To reproduce:

* Open gimp
* Create new image
* Right click on the image and select (eg) Layer and click on the dotted line (--------) that appears at the top of the menu
* Click on 'Scale Layer' on the pegged (fixed) menu that appears.

Results: Nothing happens except the 'Scale Layer' menu option becomes selected.

Expected result: the 'Scale Layer' window should appear.

This is just an example - none of the menu options work on any of the 'pegged' menus. However, if you select an option on the pegged menu that has submenu options, eg 'Transform' and select one of the options that appears, the submenu option does work.

This might be an X issue, as when you click on the gimp pegged menu option, clicking elsewhere (eg on Firefox) doesn't move focus to Firefox as expected (you have to click on the desktop or the gimp image window first).

I am able to reproduce this on Natty with gimp version 2.6.11-1ubuntu3 .

Still present in gimp 2.8.2-1ubuntu1 on Ubuntu Quantal.

I am still able to reproduce this issue with gimp 2.8.14-1ubuntu1 on Ubuntu 15.04.

However, I also tried with 2.8.14-1+b1 on Debian Sid, where the menu worked as expected after pinning it by clicking on the dotted line. So it looks like the problem is Ubuntu-specific. (I didn't see any error messages or other output when running gimp in a terminal related to this.)
