Beam over a rest bug

There's a video tutorial on how to create a beam over a rest: http://www.youtube.com/watch?v=ZERDvYKaCfk

However, in Musescore 1.1, when you do this, you will get

1) no beam over the rest,
2) the first quaver will appear wrongly like a crotchet

In the attachment, A shows the situation prior doing the operation
B shows the bug
C shows the expected result.

Workaround: first select the second quaver, change its beam to be "Middle of Beam" instead of "auto beam", then only select the rest and define "middle of beam" on it.
