Code review comment for lp:~jamesh/thumbnailer/no-fallback-albumart

Hmmm... So, when I tried running your test, it was still failing due to the incorrect signal spy. I fixed the offending source line (spy vs statusSpy, from memory), and ran the test again. This time, the test failed with lots of FAILED PREVIOUSLY errors. (I have no thumbnailer installed locally.) When I looked, I found cache files under ~/.cache/unity-thumbnailer. After deleting that directory, I ran the test again, and the FAILED_PREVIOUSLY messages disappeared, but the ~/.cache/unity-thumbnailer directory re-appeared.

It looks like some is indeed creating files under $HOME/.cache. Hmmm... Aargh...

The environment variably problem affects only the client-side, not the server side?
