Error when adding a commit with deleted file with "Diff to..." mode selected

Repro.

I will use D to denote a Delete, N to denote a 'Nothing' (no actions with the file), C to denote a Change and A to denote an Add.
Given these notations a AA means that file is added both in left branch and the right branch and DC means the file is deleted in left branch and changed in right. _Same means changes are the same in two branches and _Diff means the changes are different. For example AA_Same means that the file was added in both branches and content is the same.

We have a total number of 12 possible combinations in 2 branches: DD, DN, DC, ND, NN, NC, CD, CN, CC_Same, CC_Diff, AA_Same, AA_Diff (I have simplified the example, in real life you have 3 ways to resolve the conficts: left, right, manual... but this is already complex enough).

Branch A, we create empty files: DD, DN, DC, ND, NN, NC, CD, CN, CC_Same, CC_Diff

Branch B (from A), we modify files this way:

1. Delete files: DD, DN, DC
2. Change files:
   1. CD the content should be 'change'
   2. CN the content should be 'change'
   3. CC_Same the content should be 'same'
   4. CC_Diff the content should be 'diff1'
3. Add files:
   1. AA_Same the content should be 'same'
   2. AA_Diff the content should be 'diff1'

Lets say this commit has the hash hash1.

Branch C (from A), we modify files this way:

1. Delete files: DD, ND, CD
2. Change files:
   1. DC the content should be 'change'
   2. NC the content should be 'change'
   3. CC_Same the content should be 'same'
   4. CC_Diff the content should be 'diff2'
3. Add files:
   1. AA_Same the content should be 'same'
   2. AA_Diff the content should be 'diff2'

Now merge branch B (hash1) into C. Lets say this commit has the hash hash2. ()

IMPORTANT you need to make a change, that has not been seen yet (like resolve the conflict with 'diff3'), if you do not do so, crucible will not show your commit (if you find it manually it will say 'No files modified'). ()

Add commit hash2 into review ():
instead of all the changes from branch B you see only the 'modifications' you made while resolving the conflict ('diff3').

If you try to force crucible to compare revisions selecting "Diffs to..." in "Add to Review as" dropdown and typing hash1 in "From revision" field (), the error pops out:

Expected Result:
review should contain the same stuff that is displayed in SourceTree: 5 files, 2 deleted and 3 changed with proper changes.
