TypeError: argument must be a GstElement

[lisu]

when runing exaile 0.3.01 after build and install I got this:

$ exaile

This appears to happen because there is no replaygain elements on the system, so we dont get a valid gst.Element for the plugin. We need to catch and handle that case gracefully.

should be fixed as of trunk/2697

I have a similar behaviour with Exaile 0.3.1.2 on OpenBSD:
