Bug Description

The crashes here are often occurring when Onboard is running in conjunction to Firefox or Thunderbird. The crash occurs at the moment I try to open an appindicator menu or the Firefox/Thunderbird menu.

When the crash occurs, the whole desktop session crashes and I am back at the login screen.
