[Bug 41788] Package install fails with gconf-backends assertion

[Richard Theil]

Public bug reported:

Affects: control-center capplets-data (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed


Description:
I have been following dapper with regular (roughly daily) updates; I
can't recall having done anything strange to the packaging system or the
gconf setup, and so far it worked well. Out of a sudden, "capplets-data"
refused to install, causing dependencies like "gnome-control-center" to
fail as well. The installation returns with an error code 250 after an
assertion in some gconf backend triggers.

IIRC, the error occured with 2.14.1-0ubuntu3_all.deb, but going back to
2.14.1-0ubuntu2_all.deb by means of a manual dpkg install didn't help
either. It looks like some installation script wants to deal with gconf
data and is unhappy with the state of some setup (so this might actually
not be a problem of capplets, but of gconf).

Sorry for the german output (but you should get the idea anyway):

root at neon:/home/rich# apt-get install capplets-data
