Comment 4 for bug 821916

the fix was released in the ubuntu development version 11.10 oneiric.
But I'm not sure it will fix your skype problem, it only fixes the linking of these two plugins in xawtv.

can you test it in natty or oneiric, and report back it solves your problem.

To build and install the fix in natty do:
apt-get install devscripts equivs
dget -ux https://launchpad.net/ubuntu/+archive/primary/+files/xawtv_3.95.dfsg.1-8.1ubuntu5.dsc
cd xawtv-3.95.dfsg.1/
mk-build-deps -i -r
dch -b -v "3.95.dfsg.1-8.1ubuntu4.1~natty1" -m "test backport"
debuild -us -uc
#install all packages
debi ../xawtv_3.95.dfsg.1-8.1ubuntu4.1~natty1_amd64.changes
apt-get install -f
# or install only selected packages use these listed by: ls -ltr ../*deb with the tool of your choice

to remove the build dependencies again use: apt-get autoremove xawtv-build-deps
