ABB crashes when having to many active filters lists

Review URL(s):


When the user activates too many (c.a 10) filter lists, ABB crashes and then crashes each time the user attempts to re-launch the app.

The same behaviour can be invoked when the user has the normal English easylist installed and adds 1 additional easylist language, so that there are never more than two lists active at any time. Then, replaces the newly added list with another language. After repeating this step the 7th or 8th list added creates the same crash.


ABB 1.4.0-qa (1038)
iPhone 6 Plus
iOS 9.3.1
AA Enabled
All 'More blocking options' are disabled
URL search suggestions are Off

How to reproduce

  1. Add as many filter lists as you can


  1. Have the default English Easylist active
  2. Add the first available filter list
  3. Wait three to four seconds
  4. Disable the filter list added in step 2
  5. Add the next available filter list
  6. Continue to repeat steps 2-5

Observed behaviour

ABB crashes and upon trying to relaunch the app, it either instantly crashes again or loads to the Bookmarks screen and then crashes again.

Expected behaviour

Adding filter lists should not crash ABB.
