[Rosegarden-devel] Fixed Qt warnings on PitchBendDialogSequence

[Tom B. (Tehom) <te...@pa...>]

Fixed some Qt warnings in PitchBendSequenceDialog.  I had hoped that that
would also fix the bug where I can't hide or disable m_vibratoBox and
presumably other group boxes, but no.  When I tried that it still crashed
(segfault, no Qt warning)
