When starting linphone from the menu or from the terminal, linphone crashes immediatelly. It shows a dialog briefly,
but is closed to soon for me to be able to read it. When I start linphone from the terminal, the following error is shown:
saso@tinkpad:~$ linphone
ortp-error-MSV4l: cannot open video device (/dev/video0): No such file or directory.
linphone: symbol lookup error: /usr/lib/libmediastreamer.so.0: undefined symbol: sws_getContext

I can confirm this. After manually installing debian sid version, this problem disappeared.

Is fixed with a no-change rebuild. Given the symbol name is an ffmpeg one, and gstreamer0.10-ffmpeg recently got a no-change rebuild to pick up ffmpeg shlibs changes, I'm taking an educated guess that this is the same problem.

Fixed in 2.1.1-1build1.
