View with Panels fields embedded in Panel page doesn't display View

Hi,

not sure if this just happens to me: If I build a View with fields and display style "Panels fields", and then embed this View inside a Panels page, the view's output isn't displayed. In Views, the preview doesn't show any output, either. If I change the display style to "Unformatted" or "Grid", the view's output is there again (as well in the Panels page as in the Views preview).

"Analyze View" doesn't give any hints, watchdog log shows no errors, clearing all caches through 'admin_menu' doesn't solve the problem. Relevant module versions:

• ctools 6.x-1.8
• panels 6.x-3.9
• views 6.x-2.12

Theme: 'Magazeen' [6.x-3.0-beta1] (based on 'Fusion' [6.x-1.1] and 'Skinr' [6.x-1.6]). Checked with different browsers (Opera, FF, Chromium).

I simply have no idea where to look why this isn't working :-(

Any ideas or suggestions?
