End anchor of pedal line doesn't move to align with second voice notes

Open the attached score created from scratch with MuseScore e4004d6 on Xubuntu 14.10.

Double click on the end of the pedal line to switch to edit mode. With Shift+Left arrow", move the end anchor.

Result: the status bar shows that we're moving:

End Beat: 4
End Beat: 3.5
End Beat: 3
...

but the end anchor doesn't move.

Note that the anchor at the beginning of the pedal line is not affected by this bug. If we select it and use the shortcut "Shift+Right arrow", it moves and aligns with notes of the second voice.
