Not sure if this is an Ardour problem, or a plugin problem, but here's the
details anyway.
Ardour version: Ardour/GTK 0.534.0 running with libardour 0.835.0
Plugin: Tape Delay Simulation, from Steve Harris's 0.4.7 release of
plugins (compiled from the gentoo 0.4.7 ebuild)
To reproduce, I do the following
1. Load up a session in Ardour
2. Add the Tape Delay Simulation plugin (pre-fader) to a mono channel
track 3. Edit the plugin settings, and save the preset.
4. Close the plugin edit window
5. Edit the plugin settings and select the user preset created 2 steps back
At this point, Ardour crashes. Here is the result of "thread all apply bt"
in gdb:
Program received signal SIGSEGV, Segmentation fault.
