Problems with same view loaded in multiple tabs

[I have searched the issue queue and found similar issues but none that seemed to fit perfectly – feel free to point out if this is a duplicate.]

Using:

• Drupal 6
• Quicktabs 6.x-3.0
• Views 6.x-2.14
• Features 6.x-1.1 (view and quicktab definition live in a feature)

I have a view that takes Node: type argument. I've got a set of Quicktabs with the same view loaded in 3 separate tabs, passing arguments to filter each tab by node type. My issues:

1. When the Quicktabs are set to AJAX: yes, and the view is set to AJAX: yes, the view loads correctly in the first tab. But there are problems:
   1. Clicking the AJAX pager in the view to go to next page makes the whole contents of that tab disappear.
   2. Clicking any of the other tabs with that view shows a momentary 'Loading…' progress bar, then an empty tab identical to 1. above.
2. When the Quicktabs are set to AJAX: no, and the view is set to AJAX: yes, the view loads correctly in all the tabs. But again, activating the pager in any of these tabs makes the tab content disappear instantly.
3. I'm not even bothering to test with the view set to AJAX: no because we don't want full page reloads, obviously.

Any idea what the issue might be? I'm attaching the QT export below. Thanks!
