Comment (by raimue):

 Note that using `/login` adds another a redirect to `/github/login` first.
 I only added that because of [https://github.com/trac-hacks/trac-
 github/issues/95 trac-github#95]. The link in the navigation points to
 `/github/login`.

 I can reproduce this with a browser session that was never logged in.

 The original URL seems to be lost in trac-github with the redirects to
 GitHub for authorization and then back to the callback URL. The
 LoginModule will try to redirect back to the referer, which will probably
 be empty or the GitHub URL (have not checked). Therefore
 [https://trac.edgewall.org/browser/branches/1.0-stable/trac/web/auth.py#L253
 this redirect] drops the user to the front page without a better target.
