DescriptionVersion:
========
3.5.4699

Description:

Reproduce:
==========
See the attached screenshots for clarification of the single steps.

1) Select multiple regions
2) Combine them
3) Duplicate the newly created region
4) Uncombine one of them (e.g. the first one)
5) Uncombine the second one

Now in step 5) the region that should have been uncombined is deleted.

Just met this problem with v5.6. Yet not sure it's exactly the same problem, but yes, I do try to uncombine duplicated regions and they disappear instead of uncombining. At one time I've noticed that something was indeed uncombined, but instead turned into a 0-length region(s), which looked like fade-in/out zones clamped together. Those could be safely deleted.

I can confirm this issue is still reproducible in 5.7 using the steps provided in the description.

@timbyr: Just fyi, I had a look at how to fix that once and at that time it seemed rather complicated to me. I think a significant amount of code needs to be changed, especially the structure of how combines and duplicates are handled. The current approach seemed fundamentally wrong wrt fixing this bug.
