True. And it would be safe against write failures with GEdit's hack or

Yes it is. I also wrote an example a while ago with a similar hack, and
it worked -- will need to check which hack is the best, but still a hack...

Right. Simply using GIO would work without the hack I guess, the hack
just prevents data loss upon write failure.

I guess she's using GIO (.goutputstream-KMEUMV is a GIO name), and and
he seems to have the same problem with GEdit.
Looks like the target file was still open ("Text file busy"), so it's
either a GIO problem (failed to detect it needs closing the file on a
Windows share), an OP's problem (she has the file opened on the remote
side) or a sharing problem (whatever).
