I was attempting to clone a repository over HTTP on my dev install, but was getting a 500 returned:
```
> git clone http://phabricator.local/diffusion/TEST/test.git
Cloning into 'test'...
fatal: unable to access 'http://phabricator.local/diffusion/TEST/test.git/': The requested URL returned error: 500
```
It took me a while to work this out because there was nothing in the error logs. In order to debug this, I ended up doing this:
```lang=diff

+++ w/src/aphront/AphrontController.php

+ if ($response instanceof PhabricatorVCSResponse) {
+ phlog($response->getMessage());
+ }
}
final public function setCurrentApplication(
```
After doing this, I got some useful information in the error log:
