A couple of thoughts:

- I committed a fix for a *very* similar issue (the same assertion)
here: http://git.postgresql.org/gitweb?p=pgadmin3.git;a=commitdiff;h=9ec6b29fe3fbd9cc196d5e91b55f3697f02bcad8

- Magnus reported another similar issue when refreshing an *expanded*
"Tables" node: http://archives.postgresql.org/pgadmin-hackers/2011-01/msg00157.php

The same issue perhaps? Can you track it down with the clues in the
earlier fix and the referenced wxWidgets bug?
