[trunk r.3775] Extracted parts with wrong notes unless in treble clef

Setup: trunk rev. 3775 under:
Ubuntu 10.04, Qt SDK 10.02 (Qt lib 4.6.2)
Windows XP w/ SP3, Qt SDK 2010.04 (Qt Creator 2.0.0, Qt lib 4.7.0)

Steps:
1) Open or create a score with at least one part not in treble clef
2) Extract that part

Result: The extracted part has the clef it had in the score, but all notes are shown as the extracted part had a treble clef instead.

Dragging the correct clef (the one already shown in the part but apparently disregarded) to the first measure of the extracted part changes all the notes to the right pitch.

An image is attached showing the extraction of a part in bass clef: to have notes in the right pitch, one has to read the initial bass clef as a treble clef.

Thanks,

M.
