[Pkg-privacy-maintainers] Bug#851236: torbrowser-launcher gives python errors and doesn't launch

[Russell Coker]

Package: torbrowser-launcher
Version: 0.2.0-2
Severity: important

Here is what I get when I run torbrowser-launcher on an Unstable AMD64 system,
after displaying the following it pops up a window saying that it's downloading
and installing torbrowser and appears to hang.

Maybe there's a missing dependency on some python package or something.
