Comment 16 for bug 456530

Upgrading gavl to 1.1.1 worked for me on Karmic, Both empathy and pidgin work now, Thanks.

wget http://downloads.sourceforge.net/project/gmerlin/gavl/1.1.1/gavl-1.1.1.tar.gz?use_mirror=iweb
tar -zxvf gavl-1.1.1.tar.gz
sudo apt-get install libsamplerate-dev
cd gavl-1.1.1
./configure
make
sudo checkinstall

when prompted enter 2 and rename the package to libgavl1 and hit enter (not sure if it makes a difference or not but it worked for me)

enjoy
