Summary0004136: Crash in Addons manager Workbenches tab
DescriptionHitting down arrow repeatedly in the list of workbenches eventually causes a fatal QT error ("QThread: Destroyed while thread is still running").
Steps To Reproduce
  1. Open up Tools -> Addons manager. Make sure to be on the Workbenches tab.
  2. Click on the first item in the workbench list. Wait a second for it to load the description.
  3. Press down arrow and wait for the description to load.
  4. Repeat step 3 until the crash happens, usually within 10-15 times for me.

This is a regression to FC 0.18
