Arghh, I thought I had fixed this when I cleaned up the dbus interface. I have not had a crash since then. AFAIK there should be no data loss, as the crash happens after saving has finished. Can you confirm this?
I can confirm, that there is no data loss. All changes done are saved as far as I checked.

Git commit 4a302d8df6eb5d5bdc86f49ab11ed2987246d698 by Dag Andersen. Committed on 22/05/2012 at 11:27. Pushed by danders into branch 'master'. Fix crash due to notification during file save The reason is a notification issued in KoDocument::saveFile() which results in an async dbus message. The reply to this message can be received (timing dependent) during deletion of the dbus conection in which case it will crash. Also remove sheets.notifyrc file from sheets.
