wrong owner of /run/user/1000/dconf/user causes X to freeze

[postings@AndreasKrueger.de]

I would like to file a bug into your bug tracking system, but I don't
know which package to assign it to.
Googling shows that several others are reporting the same problems, but
the exact originator is seemingly not yet pinpointed.

Is there an open category, for bugs which are not yet assigned to a package?

Thanks for your help.

Bug report:  wrong owner of /run/user/1000/dconf/user causes X to freeze
------------------------------------------------------------------------


I have literally millions of identical log entries of this type:

    cat /var/log/messages | grep /run/user/1000/dconf/user

    Jun  6 15:54:50 laptopacer01 gnome-session[3275]:
(gnome-settings-daemon:3354):
    dconf-CRITICAL **: unable to create file '/run/user/1000/dconf/user':
    Permission denied.  dconf will not work properly.


It brings the X system to a total halt, because of:

    cat /var/log/messages | grep /run/user/1000/dconf/user | wc
    11395103 227899102 2277048187


My system is dist-upgraded from wheezy to jessie (following the manual
exactly), and that upgrade seemed to have gone fine (Kudos for that
possibility, I am pretty impressed!)

Not sure when exactly it happens; but definitely once, after purging
obsolete packages, and then 'apt-get upgrade'; and later once, after
ending eclipse.



On the console I could identify the problem to be a wrong owner:

ls -la /run/user/1000/dconf
drwx------ 2 andreas andreas  60 Jun  6 17:10 .
drwx------ 9 andreas andreas 180 Jun  6 17:10 ..
-rw------- 1 root    root      2 Jun  6 17:10 user


The error explosion stopped when I simply tried
    chmod a+rwx /run/user/1000/dconf/user

or even
    rm /run/user/1000/dconf/user

but only after
    killall Xorg
I could continue to work. After logging back in. 

(Actually, what would be a softer thing to kill than Xorg ?)



This is how it probably should look like?

ls -la /run/user/1000/dconf
drwx------ 2 andreas andreas  60 Jun  6 17:10 .
drwx------ 9 andreas andreas 180 Jun  6 17:10 ..
-rw------- 1 andreas andreas   2 Jun  6 17:10 user


So for now, my workaround is this one:

    echo "sudo chown andreas:andreas /run/user/1000/dconf/user" >
/usr/local/bin/dconf-repair.sh
    chmod 777 /usr/local/bin/dconf-repair.sh

And when it happens, I quickly switch to a textscreen console, and
execute 'dconf-repair.sh'. I am wondering if I should perhaps put a cron
job that is executing it every 10 seconds?


But: What to do?  Anyone got a good idea how to fix this?  Or how to
identify which package is causing it?  Is there a way to install a
watcher, which logs all the programs which are changing a certain file?


And: Isn't it better now to remove those 11.3 million lines from
/var/log/messages?  How?



Thanks a lot!
Andreas
