package libavcodec-extra-52 (not installed) failed to install/upgrade: trying to overwrite `/usr/lib/libavcodec.so.52.20.0', which is also in package libavcodec-unstripped-52

When I tried to run my update today, I got the following:

You might want to run `apt-get -f install' to correct these.
The following packages have unmet dependencies:
  libavcodec-unstripped-52: Depends: libavcodec-extra-52 (= 4:0.5+svn20090706-1ubuntu1+extra1) but it is not installed
  libavformat-unstripped-52: Depends: libavformat-extra-52 (= 4:0.5+svn20090706-1ubuntu1+extra1) but it is not installed
  libavutil-unstripped-49: Depends: libavutil-extra-49 (= 4:0.5+svn20090706-1ubuntu1+extra1) but it is not installed
  libpostproc-unstripped-51: Depends: libpostproc-extra-51 (= 4:0.5+svn20090706-1ubuntu1+extra1) but it is not installed
  libswscale-unstripped-0: Depends: libswscale-extra-0 (= 4:0.5+svn20090706-1ubuntu1+extra1) but it is not installed
E: Unmet dependencies. Try using -f.

This bug prevents me from updating the system.

Please, try to solve this before alpha 5 is released.

Now I get errors when trying to upgrade karmic. If I try to resolve them (or get better detail) by installing, I get:

$ sudo apt-get install libavcodec-extra-52 libavcodec-unstripped-52 libavutil-extra-49 libavutil-unstripped-49

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

If I try to install just the -extra packages:

Is that to be expected from this change? I have:

ii libavcodec-extra-52 4:0.5+svn20090706-2ubuntu1
ii libavcodec-unstripped-52 4:0.5+svn20090706-2ubuntu1
ii libavformat52 4:0.5+svn20090706-2ubuntu2
ii libavutil-extra-49 4:0.5+svn20090706-2ubuntu1
ii libavutil-unstripped-49 4:0.5+svn20090706-2ubuntu1

try:

'sudo apt-get install libavcodec-extra-52 mplayer libxine1-ffmpeg'

that should do it.

apt's dependency resolver seems to have a hard time to find the right
solution.
