This bug is clearly caused by the package 'gestreamer0.10-plugins-base' missing.
$ dpkg -S playbin gstreamer0.10-plugins-base: /usr/lib/gstreamer-0.10/libgstplaybin.so To reproduce this bug: 'dpkg --force-depends --purge gstreamer0.10-plugins-base' makes alarm-clock fail, after installing the package again it works. This affects both lenny and unstable at the moment. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
