Dear Maintainer,

Running vdirsyncer sync causes the above error message about unmatched
')'. This renders 0.4.4 - the version in stable - unusable. The root cause is that
python-click-threading 0.4.4, which vdirsyncer is depending on,
introduced an incompatibility with python-click.
More info on the problem can be found in [2] and [3].

The version in testing (0.18.0-6) is working fine as it depends on a
python-click-version that does not have the problem. So installing the
version from testing including its dependencies works.

Would you please upgrade vdirsyncer in stable to the current version in
testing to make the program work again for everyone on stable?

Cheers,

Christof
