OS: Ubuntu 12.04 LTS

After updating the OS with apt-get dist-upgrade I discovered that menu bar in wx applications are disappeared.

While in Unity there are no trouble, in Gnome-Shell and Gnome-Classic sessions the menu bars don't appears anymore.

I noticed the bug in these applications:

- Audacity
- wxMaxima

The package that has been updated are:

- libwxbase2.8-0
- libwxgtk2.8-0
- unity-lens-video
- software-center
