[trunk] Cannot drop symbols on any page except the first

Setup: trunk SVN rev. 4631; Qt lib 4.7.3; Ubuntu 11.04

Steps:

1) Open or create any score with more than 1 page
2) Drag a symbol (from the Z palette) to any page after the first

Result: in no position there any visible clue that the dropping is going to be accepted and in fact dropping the symbol has no effect.

Notes:
1) Dropping symbols on first page works as expected.
