Comment:

 Ouch! I tested here on Salut back-end (either I can't get Gabble to work
 or olpc.collabora.co.uk is not functioning). I think there are two issues:
 the first is that the timeout for the (local) Activity.Join call is a bit
 short (anybody an idea what the default is?), and two: the stream tubes
 seem to have trouble transferring the whole file. I'm not sure where the
 problem is exactly, but the GlibURLDownloader always used to work. It
 checks whether the data blocks are the expected size (4096). I changed the
 code to just check whether there is data at all, and this is the result:

 {{{

 }}}

 No more data seems to be coming, although the 'server' instance definitely
 writes the whole file.

 Any ideas?
