By that error I assume it fails to do the dynamic_cast in Calligra as well, 
due to missing typeinfo? Just that the unsucessful cast might be error-
handled, so does not result in a crash.

Your patch not tested, but looks fine to me, especially this brings 
KoSharedLoadingData now on par with KoSharedSavingData :)

Please commit to calligra/2.9 and master. Can cherry-pick to master myself, if 
you do not have that branch present.

Cheers
