[Shotwell] Shotwell crashes when importing with "Copy Photos"

[Grant]

I've been having a problem with Shotwell crashing when importing with
the "Copy Photos" option as opposed to "Import in Place" which does
not crash.  I was having this problem with 0.13.1 as described in this
thread:

http://shotwell.996238.n3.nabble.com/Crashes-when-importing-td56658.html

and now 0.14.0.  I have tried deleting .gconf/org/yorba/shotwell
(.gconf/apps/shotwell does not exist) but the result is the same.  I
get various errors in the console such as these:

(shotwell:6623): GConf-CRITICAL **: gconf_engine_pop_owner_usage:
assertion `engine->owner_use_count > 0' failed

(shotwell:14699): GLib-CRITICAL **: g_propagate_error: assertion `src
!= NULL' failed

ERROR:gconfsettingsbackend.c:205:gconf_settings_backend_remove_notifier:
assertion failed: (notifier && g_str_equal (path, notifier->path))

I'm on Gentoo fully up-to-date.
