For some reason, my session file doesn't open in latest CVS (nightly tarball) version but it does in latest beta (RPM). Ardour only says "Segmentation fault" after crashing, when trying to open this file. QJackctl : "cannot read event response from client [ardour] (Resource temporarily unavailable) bad status for client event handling (type = 5) cannot write request result to client could not handle external client request unknown source port in attempted connection [ardour:auditioner/out 1]" (I did sent this also to ardour users list)
