What functions are you using to copy the files? You probably want to use
something like gnomevfs.async.xfer, which does the transfer in a
separate thread and calls another function once its done (it also calls
a function periodically to report progress info).

Take a look at the magnatune plugin for an example of how to use
async.xfer in python. Specifically, look in MagnatuneSource.py at the
functions __download_album(), __purchase_download_update_cb() (which
gets called when "big" events happen like it's finished or an error
occurs), and __purchase_download_progress_cb() (which gets called
periodically with download progress).
