The following is done in "Expert mode" if this makes a difference.

I can reproduce this easily in 2015.0.0-beta 1:
o Create a new project
o Add two images
o Add a mask to the second image
o save the project (attached as
o press "Delete mask" in Masks

and I immediately get this:
ASSERT INFO:
../src/generic/listctrl.cpp(3367): assert "litem >= 0 && (size_t)litem <
GetItemCount()" failed in SetItemState(): invalid list ctrl item index
in SetItem

I can reproduce this by
o loading the attached pto
o changing to the Masks tab
o selecting image 1
o selecting '0 Exclude region'
o pressing the "Delete mask" button

I will try if I can reproduce this with the master. Maybe one of the
fixes you applied in the meantime has an influence.

it is disabled in my case. However, enabling it doe snot change the
assert message:

GetItemCount()" failed in SetItemState(): invalid list ctrl item index

Thank you for your time investigating this issue. Please let me know if
I can do anything else to help find the issue.
