Special characters (@) in href are not correctly handled about vdirsyncer

[untitaker]

First, I have to coment an assertion :

vdirsyncer/storage/dav.py", line 365, in list
assert href not in hrefs
AssertionError

Working on a set(), it is not a big problem.

I don't know what you mean by that. If you mean that this assertion is
unnecessary, i don't see why.

Looking into the main problems of this bug is going to take me a few weeks, i
am very busy right now.

Unfortunately i don't seem to be able to reproduce this bug. Can you give an example ics file?

[untitaker]

Ah, i do now.

Ok, thank you very much

[untitaker]

Furthermore i am not sure whether this is a bug in owncloud. Could you contact the owncloud devs (e.g. in IRC) please?

Actually this is a bug in Radicale. I filed Kozea/Radicale#158

[untitaker]

Should be fixed in master. Please run

pip install --force-reinstall git+git://github.com/untitaker/vdirsyncer.git

This actually creates a problem for me. My university's caldav-server returns properly encoded URLs containing Norwegian characters and after being 'unquoted' they aren't encoded correctly when requesting them, resulting in 404s (e.g. Gruppem%3Fte when it should be Gruppem%C3%98te). Removing all the unquote stuff fixes the problem in my case.

%C3%98 is Ø decoded, which seems to be fine. However, %3F is ? (a simple questionmark), which is surprising to say the least...

[untitaker]

@eckhart can you try the href_quoting branch?

[eckhart]

Seems to work, thanks!
