Summary	0006452: crash when scanning for plugins in a session with active plugins
Description	built from revision 4.1-364-g6dbe10d Opened a previously saved session and noticed that the VST plugins were not present. Opened preferences dialog and scanned from the plugins tab, ardour crashed. Opened same session again, selected clear VST cache from plugins tab, scanned, ardour crashed again. backtrace attached. At RG's suggestion I opened an empty session and scanned from there, no problems. After the plugins were discovered I was able to open the original session again.
Tags	No tags attached.
