[Python-modules-team] Bug#620397: python-oauth2 and python-mongoengine: error when trying to install together

[Janos Guljas]

Hello Ralf,

Thanks for filling this serious bug. I checked python-mongoengine
package and there is no need for `tests` to be available as separate
module. I am going to move that directory under mongoengine module
directory, as there are references in upstream documentation where
tests are at that location.

I am going to see with my sponsor to upload fixed package as soon as possible.

Best,
Janos
