Summary0008145: Moving gxlivelooper in strip crashes Ardour
DescriptionIf you attempt to drag and drop gxlivelooper in the strip, Ardour will crash. I've tested it from the top of the strip to several other locations within the strip, and it always crashes. I haven't tested trying to move it from anywhere other than the top because when I disable plugins, move gxlivelooper to the bottom and try to restart the session, ardour won't open. It immediately crashes.
Steps To ReproduceSee description. I can provide session on request.
Additional InformationThis is the trace when moving gxlivelooper in the strip and having Ardour crash. (below is the trace for disabling plugins, moving gxlivelooper, then attempting to start Ardour which immediately crashes).

The crash happens in gx_livelooper.so, there's probably nothing we can do about this.
A debug version of the plugin would be needed to pinpoint this issue further.

I've found that you can add a fresh instance of gxlivelooper and move it around in the strip, no problem. (I linked this bug report into the guitarix bug system, so just adding a note here for completeness).

More info:
1. I added a second gxlivelooper to the bottom of the strip and copied all the automations to it. No problem.
2. I deleted the orginal gxlivelooper, no crash, no problem.
3. I can move the new gxlivelooper instance around, no problem.
