Version:            (using KDE 4.3.1)
OS:                Linux
Installed from:    Gentoo Packages

I was compiling OpenOffice (which uses up a LOT of disk space) and my disk ran out of space. My system is on one bis partition (which is my fault, I know) so there was no space left on $HOME. After Kopete said it could not save the history for a newly opened chat, I realised that there was a problem. I deleted some temporary files, but KDE got unstable and I was logged out. So far I can live with it, but after I logged in again, my bookmarks, (only) some of the Kopete configuration, Kmail config and lots of other configs (background image) were lost.

How can this happen? If a new configuration cannot be saved because the disk is full, the old one should not get lost.

A friend told me, he had the same thing on his installation (also Gentoo, KDE 4.3.0).
