When I open the file with a BlackBox already running, I get the usual Trap
Viewer. Only when I double-click at the file to open it, I get the dialog box.

The trap indicates that the file format has been corrupted. At a place where a
new Stores.Store is supposed to start the expected tag value cannot be found.

If you open your file as data file to look at the hex dump you will find that
all the places where the file happens to contain the value 0A this is preceeded
by a 0D. This suggests that CVS may have treated your file as text rather than
binary and inserted extra CR wherever it found what looked like a LF. Such
insertions would perfectly explain why the Stores-tag is not found where it is
expected, which in turn explains the trap.

By the way: In addition to being corrupted, your file seems to be truncated as
well.

All the best,
