Subject: bus: Prevent gst_bus_add_watch_full_unlocked from a segfault if priv->poll == NULL
X-Git-Tag: 1.10.4~382
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=5048155f575856b0a5a07d95dac72b90bee9d7bb;p=platform%2Fupstream%2Fgstreamer.git

bus: Prevent gst_bus_add_watch_full_unlocked from a segfault if priv->poll == NULL

This happens if the process runs out of file descriptors. Better print
a critical warning instead of just crashing.
