telepathy-stream-engine was made for internet tables, on a desktop machine it
has always been slightly flakey as it's quite sensitive to the used gstreamer
version and doesn't cope well with error conditions.

We've been moving to farsight2 and telepathy-farsight which are a lot more
reliable then stream-engine ever was. Current empathy development releases
contain these features and should be available from the Ubuntu telepathy PPA
reasonably soon.

The rule on staying alive as a forecaster is to give 'em a number or
give 'em a date, but never give 'em both at once.
