I generally run unstable, and I did an upgrade last night, which seems to have
brought libgphoto2 to version 2.4.6-1, but gphoto2 is still at 2.4.5-2, with
nothing newer listed as currently available.  With these versions I still see
the problem I described.

Version 2.4.1-3 of libgphoto2 with gphoto2 version 2.4.0-1 (the only downgrade I
found available for that) seems to work.  Sorry I wasn't more clear about the
versions before.

I've attached the output of a successful run (with the older versions) and a
failed run (with the newer versions) here.  One thing I noticed is that with the
failed run it seems to take either several seconds or multiple ctrl-C's (not
sure which) to kill the script.
