Ever since the upgrade to shotwell-0.22.0-1.1, I can't get shotwell to ever
startup correctly.  I have a largish photo/video collection (~ 195 GB) but even
if I start with a new user account, shotwell will hang.  From my account if I
run SHOTWELL_LOG=1 shotwell I get:

Nothing happens after that (no CPU usage at all) and I eventually have to kill
it.  If I launch it as a new user (never run shotwell before) I get to the main
shotwell window with the "Welcome to Shotwell" splash screen but then it
immediately hangs with .cache/shotwell/shotwell.log showing:

I'm running the latest (as of 20150425) version of Tumbleweed and have never
seen this problem in older versions (0.21 and lower).
