[Mercurial] Compare with newest in Repository on class produces - [SubscriptOutOfBoundsError]: subscript (0) out of bounds in process NewSystemBrowser [99]

[patrik.svestka@…]

I have done two commits from Smalltalk/X. Next I wanted to check one class difference so I used the Compare with newest in Repository functionality on a ASRegistryReader class. There was a minor change in accessor, which is also used at the ::child (the Confirm warning "The same code is found in the subclass(es)..." was shown and closed via window close decoration (x))

This produces an error:

[SubscriptOutOfBoundsError]: subscript (0) out of bounds in process NewSystemBrowser [99]

Here is the walkback:
