diatonic transposition of Cb & Cbb is off by an octave
See http://musescore.org/de/node/22113#comment-83677 for a sample score and a PDF describing the issue.
It seems that whole notes with a (additional, i.e. on top of the ones from the key sig) b-accidental on ledger lines gets transposed an octave to much when transposing diatonically.
shorter notes, whole notes not on ledger lines, and notes with a #-accidental are not affected.
This might somehow be related to #21190: Ledger lines appear incorrectly positioned for whole notes or values over.

Still an issue in 916dba9
I think the original problem describe misses the point a bit. It doesn't have anything to do with length of note, ledger lines, or key. It's just Cb, period - the code for transposing that TPC value diatonically doesn't work right under any circumstances. Same with Cbb.
I've implemented a rather inelegant fix - special casing those two TPC values:

I hesitate to submit a PR as I feel there must be a better way to do this.
