I've just spent a while doing some debugging. The reason it doesn't work
is that there is no "append" method in the webdav code. So any attempts
to open a file for appending are met with the error "Operation not
supported by backend".

I see no reason why there couldn't be an append method, as there are
plenty of other webdav clients that appear to manage it. It just needs
someone to write one.

I'll have another look at this soon, but if anyone needs a pointer then
there are these:

The library gvfs uses to interface with the webdav mount:
