Summary0003478: Ardour crashes reopening a session
DescriptionHi! I'm experiencing an Ardour-2.8.11 "Segmentation Fault" re-opening a particular file. On Ardour crash it sometimes reports "Segmentation Fault" and sometimes a very long backtrace (I attached the "backtrace.txt")!

Brief history: I was working in a recording session (resizing regions) when Ardour suddenly crashed. Everytime I want to re-open that file Ardour-2.8.11 crashes!
The sequence: I launch ardour; it appears the Ardour Gui and the splash-screen with the "Reload Session History" writing; the splash disappears; Ardour-2.8.11 makes an heavy access on my internal hard drive (why? ...my session is on an external usb drive!!!) and the cpu load is beetween 85-100%; ...then Ardour crashes!

I tried to launch Ardour with the options "-d", "-O", "-S", but no success.
I tried to open that file by using Ardour2-svn and Ardour3-svn but with no success..also these new Ardour versions crashed!
I tried to open that file by using Ardour on a gentoo distro (totally removing the memlock) but unfortunately with the same result!

I could re-open successfully the session by changing the zoom="..." value in both "instant.xml" files. The one in my ~/.ardour2 and the other one in the session directory.
Specifically, I couldn't load the session with the value "zoom=257.000000"; I had to change to "zoom=2048.0".
Thanks for the help received in the "#ardour" irc channel!! :)
