Thanks for looking into this.  I've added some profiling checkpoints
to the code in svn.
My initial results are here:

I agree we should defer construction of the language dialog.  We used
to start the settings daemon asynchronously but changed it to avoid
having settings/themes change after the dialog had already come up.
Maybe we should revisit that decision.  Probably also worth spending
some time to profile and optimize g-s-d startup.
