Right now the best way to solve this would be to detach imgbin from the rest
using appsrc/appsink. Then we can even have a pool of imagebins and we can
control the states without g_idle_add.

For the record, if we just remove the g_idle_add as it is now and make a direct
call, we get stuck in.

gstbasesink.c:4741       GST_PAD_PREROLL_LOCK (basesink->sinkpad);

Maybe there is a easier fix then then appsrc/appsink change.
