Main menu disappears after exiting Preferences.

Tested with
Audacity 1.3.13,
Audacity 1.3.14 svn Nov 18th
Audacity 1.3.14 rc1

Debian Squeeze with Gnome 3 and Gnome Classic (fallback)
Also tested on Debian stable in VM with same results. Debian Stable uses Gnome 2, but it is running as a virtual machine in Debian Squeeze which uses Gnome 3.

Steps to reproduce:

  1. Open Audacity
  2. Open Preferences (Ctrl+P or from menu)
  3. Close Preferences (Enter or click on “OK” button)
    The main menu disappears leaving just “Fi” showing (screenshot below).
    The menu does not disappear if the “Cancel” button is clicked.
    The menu returns to normal as soon as the window is resized.

Title updated as this bug is not specific to Gnome 3 (as the previous title suggested).
