Inserting Measures Screws Up Playback if There is a Subsequent Time Signature Change

Hello.

My System:
-Ubuntu 9.10
-MuseScore 0.9.5 Stable

The bug:
When you have a time signature change, inserting a measure before that time signature screws up the play back.

To reproduce:
1) Create a score like the first attachment (beforeinsert.mscx), or simply open it. Note the time signature change. When you playback the score, it sounds normal.
2) Insert a measure before measure 2. (Select measure 2 and press the INS button).
3) Play the score. Notice how the notes in the third measure start playing before the notes in the second measure are done.

This only happens if there is a time signature change following the insertion.

You can also look at my second attachment, afterinsertproblem.mscx, to see the result of the steps listed above.

Thanks,
Isaac.
