bug-buddy backtrace report

I'm trying to test 0.14 for upload to Debian but whereas the plain buzzer
works, trying to specify a different sound file (and use the GStreamer
support), causes gpe-announce 0.14 to crash.

I suspect it is related to the build message:
callbacks.c: In function ?play_url?:
callbacks.c:475: warning: passing argument 1 of ?gst_bin_add_many? from
incompatible pointer type

gpe-announce-0.14$ ./gpe-announce "test" /usr/share/sounds/startup3.wav

Is there a reason why gpe-announce uses a dlopen for this functionality instead
of building against the gstreamer library and using the function calls
directly? (maybe using a ./configure switch so that this code is not loaded
unless built with the option enabled?)

I'm attaching the report from bug-buddy which is triggered each time.

A secondary problem is that any second argument to gpe-announce causes a crash,
whether that is a sound file or just junk. gpe-announce should check that the
second argument is a file before trying to pass that to gstreamer.

I've simply commented out the argv[2] handling in main.c for now, leaving the
Debian package with only the default audio buzzer. Other Debian changes can be
viewed at:
http://patch-tracking.debian.net/package/gpe-announce/0.13-2
The latest changes will appear at:
http://patch-tracking.debian.net/package/gpe-announce/0.14-1
once the upload has been processed.
