Pidgin Helper not showing unread messages

Making a deeper research and having a look to the code, I've ended at this web page:

http://developer.pidgin.im/ticket/12507

It seems that the method used in the helper, "PurpleConversationGetData" isn't exported through DBUS by pidgin anymore.

I'm working on a change to the helper to obtain the number of unread messages through the pidgin API. If I have success, I'll post it here.

I found a workaround, that you can use if you're having the same problem and you miss the unread messages badge on pidgin 2.7.11 as I did:

- Go to Administration/System and open Synaptic Package Manager
- In the text box, search for "libpurple"
- You will find two packages, libpurple-bin and libpurple0. Select them, and go to the menu "Package-->Force version"
- In the dialog box that will appear, select version: 2.6.6-1ubuntu4, and click on "Force version"
- Click on the button "Apply", and restart Pidgin. The pidgin helper will behave now as usual, showing the number of unread messages in the badge.

The workaround mentioned above does not offer 2.6.6 any more to me on ubuntu maverick, all i get was 2.7.3, and this one is affected too:

Log see below:

(Now google should find this report when somebody search for the message in google too... ;)

Sure, I forgot to specify that my workaround was only tested on Ubuntu 10.04, Lucid Lynx. Maybe adding the purple repos for lucid to maverick you could get the 2.6 packages. Or if somebody wants them, I can upload to any host.

Have exactly the same issue, with the same trace :( Is there some workaround with maverick?
