Thanks for your report!
This is a known bug that plagues all of Calligra :-( and which so far could not be located, as it only happens for a few, but not for developers. Somewhere on autosave it crashes sometimes for whatever reason.

Looks like things are better with the new version 2.7.x, so please update as soon as possible and continue reporting any issues.
