Totem: loading "Coherence DLNA/UPnP Client" results in: "ImportError: No module named coherence.ui.av_widgets"

After installying "python-coherence", the GUI bug stays the same, the CLI output is more ugly and/or more informative.

Solution (workaround?) found, thanks to Linux genius ArjanW drinking my Bavaria beer:

As root, create file /usr/share/dbus-1/services/org.Coherence.service with contents:

[D-BUS Service]
Name=org.Coherence
Exec=/usr/bin/coherence -o use_dbus:yes -o controlpoint:yes

After that, totem's Coherence DLNA/UPnP can be activated.

HTH

And a picture showing that the totem Coherence DLNA UPnP actually works; it does see the UPnP AV Mediaserver provided by rhythmbox.

Confirming, also workaround proposed works here.

is that still an issue using the new coherence version?

Sebastien,

I checked and the error still occurs: totem -> edit -> plugins -> conherence
results in "Unable to activate plugin Coherence DLNA/UPnP Client".

However, I'm not sure anymore that I'm actually running BETA (see below),
so, just to be sure, I will get the Jaunty-Beta-CD, boot that and report
back.

n.b. this is marked LOW priority, but it is one of the headline updates for Jaunty - people will look out for this feature.
same for me, even with the following workaround in place:

/usr/share/dbus-1/services/org.Coherence.service

[DBUS Service]
Name=org.Coherence
Exec=/usr/bin/coherence -o use_dbus:yes -o controlpoint:yes

totem --version

I tried the apres-BETA daily build of March 31, and that gives the same
error messages when trying to activate the Coherence-plugin in totem.

I had to activate universe + mutiverse, then install python-coherence by
hand (and edit /usr/share/dbus-1/services/org.Coherence.service) to get tot
Coherence/DLNA plugin in totem working.

So: AFAICS, nothing has changed since my bug report.

coherence is not installed by default due to CD constrains so I doubt that will be an highlighted jaunty option

the issue seems to be a coherence one

Well, yes, it is *by subject* a coherence problem. But this bug report reveals two bugs:

bug 1: the fact that totem offers Coherence DLNA/UPnP, whereas python-coherence needs to be installed for that, which does not happen.
If is not installed by default due to CD constrains, it should not result in an ugyly error.

bug 2: installing python-coherence reveals a bug in bug-python itself: the missing file. To avoid confusion (!) I've reported a separate bug report for the second bug, see https://bugs.launchpad.net/ubuntu/+source/coherence/+bug/352653

By solving only bug 1, you will still have bug 2.
By solving only bug 2, you will still have bug 1.
So, two separate bugs.

@Sebastien Bacher

What do you mean with "I doubt that will be an highlighted jaunty option"?

Do you think the coherence plugin is not offered by the totem GUI? If so, please see the included screendump where coherence is offered, including the GUI and CLI errors I get by 'checking' on the plugin.

oops, typo:

"installing python-coherence reveals a bug in bug-python itself"

should read

"installing python-coherence reveals a bug in *python-coherence* itself"

The issue is with totem.

Reason: coherence plugin is shipped in totem-plugins package which must not require universe/multiverse packages to work. the plugin needs python-coherence, which is in universe. I'm working on moving the plugin to totem-plugins-extra, which is a package available for this purpose.

debdiff attached:

totem (2.26.1-0ubuntu3) jaunty; urgency=low

  * debian/control
    - add Depends in totem-plugins-extra for python-coherence to make
      the coherence-plugin work (LP: #338963)
    - add Replaces for totem-plugins and totem-plugins-extra since the
      coherence-plugin is moved to -extra
  * debian/rules
    - move the coherence-plugin from -plugins to -plugins-extra
