This also arises under NT (with different circumstances):
Start with a single frame.
Press the news button.
Minimize the original frame.
Click the Exit Gnus button.
The result: "Attempt to delete the sole visible or iconified frame"
Can you also reproduce this with frames created by C-x 5 2 ?, i.e.
C-x 5 2
C-x 5 o (little ooo)
minimize other frame
C-x 5 0 (zero)
