*** This bug has been marked as a duplicate of bug 324447 ***
Could you please give some more information like how often does this happen, do you remember what you were doing before this happened? Also providing an anonymous file would be nice.
I lost all my data because of this bug. I was just working with credit card account adding and tagging some records, when I clicked on save button and then it crashed. It would be good add a cache version of kmy file, this way Kmymoney could recover my data not destroy all of them. OpenSUSE 12.3 and Kmymoney 4.7.1 - kde4 4.10.5 "release 1"

How? Kmymony destroy(empty completely) the kmy file file at the crash! But if Kmymony had a cached version of my file ex.: .cache/kmymoney/[kmy user file] And we could help providing that file. > Can you produce an anon file, as requested in comment #2? Do you want the empty file?

<snip> > Did you know about the "Number of backups to keep (0=off)" option from the > "General" settings page? Also, you can specify the frequency of backup. To stand a chance of finding a bug, some evidence will be needed.

No! I used to read the manual[1] and do my work step by step. After the crash I've searched for something in the manual and didn't find anything about this option [2]. Where does it save these copies? Now I've activated it, so if the crash occur I will send the file.

Jack: could you add a note to mention this to the user documentation TODO list? > Where does it save these copies? in the same directory as you kmymoney file.
