I did, and if it were a duplicate I wouldn't have opened the bug (and referenced bug #641378 in the comment #0). Regardless of whether the final solution or fix would be identical, it's not the same bug per se. Bug #641378 is about digikam failing to build against kcalcore, whereas this is about upgrading kcalcore to 17.12.0 silently breaking the digikam installation by causing a run-time linking error.
Shouldn't revdep-rebuild or @preserved-rebuild have caused a rebuild digiKam in this case?
In theory yes, since there is a soname change with every kcalcore point release, but I haven't checked linking yet (I hadn't set up digikam with USE=calendar).
Yeah, just links against libKF5CalendarCore.so.5.
