Not sure.  The only thing I can suggest is that perhaps you aren't allowing
sufficient space for the directory which holds the index files (configured
somewhere in the preferences).  If this is too small I guess it's possible
that some index files in use might get deleted as other media are added to
a project.  It wouldn't have to be the same project either; if you had two
projects (A and B), did work in A for a while and then swapped to B to do
some things in that, it's possible that adding clips to A might cause index
files used by A to disappear - and then you do get flatlines in your audio
waveforms.

Having said that your symptoms don't exactly match this scenario.  However,
it might be worth checking anyway.

Only that under heroine's CV I've noticed similar problems on load from time
to time.  For me it seems that cinelerra simply locks up part-way though
loading a project.  The precise point of the lockup isn't consistent.  I've
had lockups when:
 * no media has appeared in the resources window at all
 * some or all media has appeared in the resources window
 * some timelines have been drawn in whole or in part

I don't have to reboot to get a successful load however - I just ctrl-C and
try again; usually I get a successful load after one or two attempts.  I've
never left things long enough to see if cinelerra actually crashes out of
its own accord.

Circumstantial evidence from tests I've done suggests that having "draw
media" activated makes the bug more likely to trigger.  For me the problem
first appeared after I upgraded my machine to Slackware 10.x from an earlier
version of Slackware (sorry, can't recall the versions off-hand) and
upgraded Cinelerra to v2.1.  Thus I can't be sure whether it's a problem
triggered by cinelerra 2.1 or the newer glibc which is now in use.  In any
case, if I had to take a stab at what is happening I'd say there is some
kind of race condition or locking error between the thread which reads the
project in and the code which draws the media.

Machines I've seen this on are an 866 MHz Pentium3 and a 2 GHz Centrino
(Dothan) laptop.

I'll see if I can dig up a dump from one of my ctrl-C events; that might
show whether we're talking about the same bug.

In regard to what?  The use of Athlon-64?  I can't say, except to point
out what I've written above.
