Bug#934376: gstreamer1.0-pocketsphinx: fails to load due to incompatible version

[Stéphane Alnet]

Package: gstreamer1.0-pocketsphinx
Version: 0.8+5prealpha+1-3
Severity: grave
Justification: renders package unusable

Dear Maintainer,

After installing the package, the `pocketsphinx` plugin fails to load.

It appears that the plugin is incompatible with the version of gstreamer
available in `testing`:

```
GST_DEBUG=4 gst-inspect-1.0 /usr/lib/x86_64-linux-gnu/gstreamer-1.0/libgstpocketsphinx.so
[...]
0:00:00.063752136 31079 0x5645debd2c00 WARN      GST_PLUGIN_LOADING gstplugin.c:486:gst_plugin_register_func: plugin "/usr/lib/x86_64-linux-gnu/gstreamer-1.0/libgstpocketsphinx.so" has incompatible version (plugin: 1.16, gst: 1,14), not loading
Could not load plugin file: File "/usr/lib/x86_64-linux-gnu/gstreamer-1.0/libgstpocketsphinx.so" appears to be a GStreamer plugin, but it failed to initialize
```

To summarize: gstreamer is currently 1.14 in testing but 1.16 in unstable;
the pocketsphinx module is built using gstreamer 1.16; gstreamer 1.14
refuses to load a plugin built with gstreamer 1.16.

After installing the version of gstreamer available in unstable, the
plugin loads properly.

I suppose this could be fixed by updating the dependencies to match the
package's actual build dependencies, for example
  libgstreamer1.0-0 (>=1.16.0)
but I assume there may be better ways to do this.

Best regards,
Stéphane
