[Sebastien Bacher (seb128)]

setting to High, it's one of the most frequent unity issues on errors.ubuntu.com

[Alberto Salvia Novella (es20490446e)]

Since this bug:

- Is valid.
- Is well described.
- Is reported in the upstream project.
- Is ready to be worked on by a developer.

It's already triaged.

[Łukasz Zemczak (sil2100)]

It also seems to affect the daily-release process, as it is breaking some of the indicator tests.

  * Workaround for crash in unity-panel-service. The Edit Undo test
    didn't work due to the bug LP #1063212 in unity-panel-service. This
    should avoid it entirely. (LP: #1063212)
  * Export menu item icons.
