Ardour crash when removing lv2vocoder from favorite plugins

I’ve just built Ardour2 with LV2 support and was playing around when I accidentally bumped into this issue:

  1. Open the Plugin Manager;
  2. Tick in the favorite checkbox for the LV2 vocoder plugin;
  3. Untick the favorite checkbox for said plugin;
  4. Ardour2 crash.

When I took a look in the ~/.ardour2/favorite_plugins file I found this line:

AudioUnit http://home.gna.org/lv2vocoder/1

That should really only read:

http://home.gna.org/lv2vocoder/1

All the swh-lv2 plugins behave normally, it’s only the vocoder that Ardour mistake for an AudioUnit plugin.

Weird, uhu?
