problem with schema-awareness for backup/restore

Hi all

I have something similar like this situation w/ PgAdmin 1.4.0 :

Database X  has two schemas: A and B. In both schemas, there is a table named C.

Now when I the schema B in the left-hand tree, then right-click on the table C therein and select "Backup", PGAdmin III
willdump the table in schema A. It simply forgets to add the -n switch to the pg_dump command line. 

Is this a known bug?
