Transposing causes massive layout problems (attached score)

I created the attached file in MuseScore 1.2 and opened it in the latest nightly build (MuseScoreNightly-2012-08-07-ce351a2.7z). It loaded ok, looked just fine.

Then I tried to transpose it to the key of E, and the layout was completely hosed. See attached file for results.

I transposed by following these steps:
1) load the file
2) go to the menu Notes/Transpose, then "transpose entire score"
3) Leave Transpose by Key selected, and mark the Up radio button.
4) Change the key (in the drop-down) from G major to E major.
5) Select "single sharps and flats only" (in the drop-down)
6) Click OK.

Resulting score has multiple problems, including:
* Measure 10 goes off the left-hand margin
* multiple barlines in a row right after Rehearsal A, and notes overlapping the key signature and extra barlines
* Rehearsal A is not the first measure on the line, but still has a key signature and clef symbol
* gliss markings are stretched inappropriately
* Stems of grace notes in measure 65 overlap the beams of the "regular' notes they are next to

When I followed the same steps in MuseScore 1.2, the only problem was the inappropriate stretching of the gliss symbols. None of the other layout problems appeared. On the other hand, when I open the file produced by 1.2 with the nightly build exe, I see the layout problems listed above.

Also, when I do the transpose in version 2.0, and save the file, and then reload it, the problems around Rehearsal A are slightly different.

I'm using Windows 7, by the way.
