You are not required to ask the daemon each time. You can just first
lookup the thumbnail path for an original, and if it's not there you
could ask the thumbnailer to make it for you. And then it'll tell you
when it's finished with that.
That's also the recommended way. Calculating an MD5 is less expensive
than doing a DBus method.
Of course is this a task for a toolkit specific library that does
thumbnailing for your application developers.
