Changing # parents on TASK BOARD can get you "stuck"

Hi,

One of our users reported a bug to me and I have reproduced it in GH 3.0.1 and GH 3.4-EAP-jira39 (on the greenpeppersoftware.com website).

Recipe:

1. Browse to TASK BOARD
2. Switch to Outline view
3. Set # parents to 1
4. Browse to the last page of issues
5. Set # parents to number of pages + 1

Now the paging links disappear but the view doesn't show any more issues than it did before.

Cheers,

Ximon
