apt-get xchat: cannot find gconf-schemas even if it is installed

["massimo s." <devicerandom@gmail.com>]

Hi everyone,
another packaging quirk, this time with xchat:

----
Setting up xchat-common (2.6.8-0.3) ...
/var/lib/dpkg/info/xchat-common.postinst: line 5: gconf-schemas: command
not found
dpkg: error processing xchat-common (--configure):
 subprocess post-installation script returned error exit status 127
dpkg: dependency problems prevent configuration of xchat:
 xchat depends on xchat-common (= 2.6.8-0.3); however:
  Package xchat-common is not configured yet.
dpkg: error processing xchat (--configure):
 dependency problems - leaving unconfigured
Errors were encountered while processing:
[snip other to-do packages]
 xchat-common
 xchat
E: Sub-process /usr/bin/dpkg returned an error code (1)
----

gconf-schemas is present in /sbin .
xchat can be launched, but it hangs and no GUI appears.


Any hint on what to try?

Thanks,
m.
