New issue 135: Forking a git repository hangs in infinite loop
https://bitbucket.org/conservancy/kallithea/issue/135/forking-a-git-repository-hangs-in-infinite

Matthias Zilk:

Forking an existing git repository on a new installation of kallithea hangs with the message
```
Repository "test-fork" is being created, you will be redirected when this process is finished. 
```

In the log the following 4 lines 
```
#!python
