Broken dependencies

[JD]

Hi,
After I added my preferred ppa for ffmpeg, running updater
declared things broken, with the following error message:

The following packages have unmet dependencies:

kmediafactory:

                Depends: libthreadweaver4 (>= 4:4.3.4) but

This is rather nasty, because even if I resolve the problem with 
kmediafactory,
probably yet another package will have some dependency problem.
