Menu bar not visible under Unity

[Jens Li]

Version: Exaile 0.3.3.0-dev+bzr3898
System: Ubuntu 11.10
Window manager: unity 4.24.0

The menu bar at the top of the window is not visible. Neither at the top of the Exaile window, nor in the "Unity bar" at the top of the screen.

When running the repository version, Exaile 0.3.2.2, the menu bar is visible in the "Unity bar" (when pressing alt-key, or on mouse over).

When running Exaile 0.3.3.0-dev+bzr3898 on a computer with the Lubuntu 11.10 operating system (LXDE window manager), the menu bar is visible and works fine.

This seems to be caused by some incompatibility with the Unity menu system, where the menu bar is located at the top of the screen (not at the top of the application window).

When running Exaile 0.3.3.0-dev+bzr3898 on Ubuntu 11.10 the following log is printed. Note the assertion warnings from GTK.

A workaround is to run Exaile with the environment variable UBUNTU_MENUPROXY set to 1.

UBUNTU_MENUPROXY=0 ./exaile

This makes the program to get the menu in the traditional place, at the top of the application window. Then it works as expected.

Sorry, i mean UBUNTU_MENUPROXY set to 0.

As in the example.

I'm sure this is a Unity bug, but workarounds are welcome.

Affects monodevelop-4.0/xamarinstudio as well on 12.10
W/A with UBUNTU_MENUPROXY=0 helps.

I can confirm this bug under Ubuntu 13.10.

[Facundo Batista (facundo)]

Happens to me also in 13.10

[Johannes Sasongko (sjohannes)]

Seems to be working now. Unity 7.2.0, Exaile 3.4.0-dev+bzr4422.

[Thomas Hotz (thotz-deactivatedaccount)]

I have tested this with Exaile 3.4 in Ubuntu 14.10 and it is fixed.
