KMyMoney keeps the original file as long as possible. Saving the data only 
happens when

a) the user hits the save button and data had been changed
b) the user wants to quit the program but data bad been changed
c) autosave is enabled

In any of those cases, KMyMoney writes the new data into a temp file and only 
if this is successful replaces the original file with the temp file.

Not really, see above a more detailed description about that temp file usage.

I doubt that the changing the report and running into a crash causes the file 
size to be modified. Unless - and we have seen this before - the program was 
not built correctly and installed using binary packages.

The backup part that Brendan was talking about is external to KMyMoney. 
Consider looking into the contrib directory which contains e.g. my version of 
a backup mechanism. In fact, I have 1569 backup files dating back to the old 
days. It's name is "thb.kmy-2005-10-19-21-20-02".
