Comment (by dido):

 OK, I get what's breaking up generalization.

 Talking about test1.png - it's a piece of polygon boundary that's several
 hundred meters in length, unfortunately causing a self-intersection. Why
 v.generalize discards the whole polygon side that's several kilometers
 long but not the problematic sector only?

 Actually in my first tryout the whole area was not fishnet'ed to 5000x5000
 m cells so  small problematic sectors resulted to tens and hundreds of
 kilometers of shoreline being not generalized at all, making the tool
 completely unpredictable in the output.
