Fail to build Pidgin 2.14.1 on Debian 7 and Gstreamer 0.10

[Zenitur]

There is the error:

Thanks dwmw2_gone from an IRC chat for a fix:

I hope than this fix will be applied in Pidgin 2.14.2

Also EionRobb helps me to fix building with some old GStreamer 0.10 version by changing:
"caps = gst_pad_get_current_caps(mixer_srcpad);"

with:
"caps = gst_pad_get_caps(mixer_srcpad);"

I hope that this thing is also in the trunk. It's also need some condition like "if gstreamer is lesser that some version, else..."
