I can't count
I'm a musical ignoramus, but I thought that the note lengths decreased by half. So I expected that the duration of the notes in this measure 
As you can see, it isn't. Indeed, in the printed sheet from which I am copying, they are identical. What am I doing wrong?
This is with both 2.0.2 and the 2.0.3 unstable on OS X Yosemite.

They should indeed be of the same length, so that quarter rest in top staff is too much. Might be that some corruption crept in. Could you share the score?
Maybe the last half notes chord in top staff is really just quarter notes with a half note head?

I not that the measure duration actual is 20/4, which seems odd. I also have a cut-down version contains just this measure, if that is preferable.

The measure in question does have 20/4 duration.
Using the Inspector, look at Note -> Head type for the notes on beat #14 of both staves. The head type is set to 'Half'. Click the arrowed button to reset (actual quarter notes).
Also, the very next half note chord in the top staff has the same issue.
You will have to increase the measure duration to hold actual half notes.

For me, in the Inspector, they're set to auto. Aren't they supposed to be 1/8 notes? There is no option to manually set to Eighth in the Inspector. That in both 2.0.2 and 2.0.3 unstable.
In reply to For me, in the Inspector, by pbw
AUto is the normal setting for note heads, and one should never normally need to change that. This option is only needed in very cases where you a note to *act* like one duration but *appear* like a different one in terms of which note head is used. An eighth note has the exact same note head as quarter, so tht is why there is no separate options for both of them. The quarter note head *is* the eighth note head, but again, you shouldn't normally ever be messing with this.
There's deffo something awry here.
WOuld it be possible to post an image of the original?

Here's the original, and I notice that there are a couple of errors, but on notes of the same length.

The notes on beat 14 appear als half, but are quarter. Select one note on beat 14 (upper line) and press "6", do the same on lower line. Then you have to reenter the last few notes, but the counting is ok.

Thank you. Had I looked at the lower status line, I suppose I would have seen that.
Any idea how such things occur? Should I report a bug?
In reply to Thank you. Had I looked at by pbw
I think you accidentialy changed the noteheads to half. If so, i don't now how you did it. Can't imagine MuseScore did it automatic.
