Comment 3 for bug 939126

We see it all the time in KDE Telepathy with users who only have telepathy as the app that uses libdconf.

Telepathy gabble quits with:
"unable to create '/home/username/.cache/dconf'; dconf will not work properly"
The issue is in dconf_shmdir_from_environment() in libdconf.

It doesn't seem to affect Gnome users very much as some other app will have created this directory first.

I did miss a step in my instructions:
make sure you disconnect any jabber accounts (as otherwise telepathy-gabble will automatically spawn after you kill it, before launching by hand)
connect the jabber account after launching telepathy-gabble manually, this is when the error occurs.

I'm using Oeneric, but I think this still happens in precise as it was brought up on the kubuntu-devel ML when talking about telepathy.
