Summary0008727: Crash when opening old session
DescriptionI'm trying to open some old sessions, but ardour crashes before managing to open them. Attached backtrace of opening both normal and safe mode.

x42 mentioned on irc that the error message seemed to indicate a track without a playlist, but that doesn't seem to be the case if looking at the session file.

The original session file was copied to a "-2000.ardour" file, but this file is identical to the original, including "Session version="2.0.0"" at the top, so I suspect that the origin error is a failure to convert the session? I will include both files on this issue.
Steps To ReproduceOpen the session, ardour immediately crashes.
Additional InformationBacktraces created from version 6.7.25 from nightly.ardour.org
TagsNo tags attached.

Fixed in 6.7-56

This session misses a playlist/diskstream for the track "Audio 1". Apparently all recording were move to other tracks and the original playlist deleted.

Probably my workflow did this, as I had the same problem with all old v2 sessions. Can confirm that this fix enables me to open them all and save them to the new session format, which enables regular 6.7 to open them.
