      Description

      To reproduce:

      1) Open Preferences dialog and select Documentation tab
      2) Scroll down the list and click the last doc
      3) Press the Shift button and click the first doc - this way all docs got selected, but in reverse order
      4) Click Remove button, confirm the message box (if necessary) - crash.
