Version:           4.5.1 (using KDE 4.5.5) 
OS:                Linux

I built it using a slackbuild packaging script from http://slackbuilds.org

It used to crash a lot while editing a split transaction.
And several days ago, I tried to save changes to a kmymoney file.
It crashed and saved a zero-length file on the original file.
Since I didn't have any backup, I lost all my kmymoney data and have to make a
new kmymoney file again.

When it crashed while editing split transaction, it involved ibus(an input
method engine).
Because I forgot to record the crash report when it crashed, I can't verify if
this bug is also related to ibus, but I think it could be related to ibus.

This again reminded me of the importance of daily backup.

Please help fix this bug.
