[Bug 1246536] Re: segfault in menu_hidden()

 

** Description changed:

+ Impact: indicator-sound is segfaulting the unity-panel-service sometimes
+ 
+ Test Case:
+ - install the current GTK version from saucy-proposed
+ - use the indicator-sound slider and the play multimedia key to start/stop rhythmbox
+ - the indicator should be stable
+ 
+ Regression potential: try desktop indicators and make sure they keep
+ working
+ 
+ -------
+ 
  Using saucy stable, happened a few times today while using the slider,
  muting/unmuting, using play multimedia key/mpris to start/stop rhythmbox

Title:
  segfault in menu_hidden()

Status in Sound Menu:
  Fix Committed
Status in “ido” package in Ubuntu:
  In Progress
Status in “ido” source package in Saucy:
  In Progress

Bug description:
  Impact: indicator-sound is segfaulting the unity-panel-service
  sometimes

  Test Case:
  - install the current GTK version from saucy-proposed
  - use the indicator-sound slider and the play multimedia key to start/stop rhythmbox
  - the indicator should be stable

  Regression potential: try desktop indicators and make sure they keep
  working

  -------

  Using saucy stable, happened a few times today while using the slider,
  muting/unmuting, using play multimedia key/mpris to start/stop
  rhythmbox
