I think I've concluded (i.e. made an educated guess) that this might be 
due to an invalid path name - most likely happening in a non-English 
locale.  ARDOUR::Session::cleanup_sources() calls g_stat(), passing a 
pathname string and the address of a GStatBuf. On Windows, the first 
thing that happens in g_stat() is that the pathname gets converted fro 
UTF8 to UTF16.  If that conversion fails for some reason, g_stat() will 
return an error status, leaving the statbuf uninitialized.  Currently 
however, we ignore this and carry on regardless.  I think that's most 
likely why users are seeing the weird figures.

I've pushed commit #83b48f5cc4.  It's a small fix to check the returned 
result from g_stat().  Hopefully that'll tell us if my guess was right...
