After selecting Tools | Add-ons menu the "Addon manager" window appears, but it is blank regardless the choice on the left column. All the controls in the top area seem to be non-functioning. 

If I click the two wheels button a pop up menu appears, but every item of the menu (including "Check for updates automatically" toggle) does not work.

Reproducible: Always

Steps to Reproduce:
1. Select Tools | Add-ons menu item
2. Try to click in one of the items of the window that pops up

Actual Results:  
The "Addon manager" window is blank

Expected Results:  
The "Addon manager" window should contain some items, especially the "Extensions" section, since I ha some working extension installed.

OS is latest Ubuntu x86_64 with all patches applied
