When is it safe to Quit?

[Dougie Nisbet <dougie highmoor co uk>]

I notice that starting f-spot on the command line gives me lots of 
information about what's going on. Often it chatters away even though I 
have finished an operation and f-spot has given me back control. e.g. 
Multiple tagging.

Is it safe to Quit while there is activity in the terminal window? For 
example, I notice occasionally I get messages such as
> (f-spot:14532): GdkPixbuf-WARNING **: GdkPixbufLoader finalized 
> without calling gdk_pixbuf_loader_close() - this is not allowed. You 
> must explicitly end the data stream to the loader before dropping the 
> last reference.
even though there appears to be no adverse effect.
