[Shotwell] Slow Import with many duplicates...

[Lucas Beeler]

Hi Ken,

As Norbert noted, some of the problems you see may have something to do
with an interaction between the Shotwell import subsystem and your
particular memory card or card reader. That said, this error:

> Photos/Videos Not Imported Because Shotwell
> Couldn't Copy Them into its Library:

Is almost certainly due to the permissions problem on the library
destination directory that you described in your message. You also asked
this question:

This is covered somewhat in the "Can I access a Shotwell library across a
network, possibly from multiple machines?" section of the Shotwell FAQ
here: http://redmine.yorba.org/projects/shotwell/wiki/ShotwellFAQ. While
the FAQ entry describes one specific and particularly dangerous problem,
sharing the same library directory between multiple Shotwell instances is
not recommended or supported.

Cheers,
Lucas
