Bug#692991: [dconf-tools] File: ~/.config/dconf/user becomes corrupted and breaks account

[Julian]

Package: dconf-service
Version: 0.22.0-1
Followup-For: Bug #692991

Problem still exists. ~/.config/dconf/user is getting corrupted continuously
and the Desktop environment freezes after login (in my case MATE: mate-panel is
using all cpu but is not showing;  everything else stops loading; grafical
artifacts (maybe parts of the panel) can occour). Ctrl-Alt-Backspace, deleting
the user-file and replacing it with a backup works. The md5sums of the
corrupted file and the backup of course differs, although no changed should
have been made.

I noticed the following actions than may trigger this (but don't have to - I
wasn't able to reproduce it every time, but it's very likely to happen):
- I'm using a setup with two monitors. Booting without the second corrupts the
user file
- "Playing" with xrandr (changing the setup, without saving it) can corrupt the
user file. Also the xrandr setup can't be changed anymore until rebooting in
that case.
- Some system crash (failing to enter sleep mode for example) corrupts the file
and of course
- changing dconf settings can corrupt the file, without any reproducable
pattern

Not sure but maybe the fact that I'm using multiple monitors and MATE (now
1.8.1+dfsg1-3) has something to do with it, due to the actions that triggers
it.

I think this problem is more related to dconf-service instead of dconf-tools.
But this bug report already existed so I won't file a new one.
