[Shotwell] 0.8.1 update: Problem with CR2 files from a Canon EOS 550D

[Jim Nelson]

Yes -- now I see what is going on.  I noticed that the libraw libraries were
.a files, but I thought they contained .so and that this was some Linux-ism
to compress shared libraries.  Now I see they're .o files, so in fact
Shotwell *is* statically linking them in.

<sigh>

This changes the game quite a bit.  This means libraw is purely a build
dependency.  Users can't merely upgrade libraw, but need to rebuild Shotwell
as well.  I thought the bug fix was due to a header change, hence the need
to recompile.  It's more fundamental than that.

I've posted a message with the libraw folks to get them start thinking about
this issue: http://www.libraw.org/node/544
