Description of problem:
I'm trying to import a package that has only a master branch. First of all autocompletion for the path to the srpm does not work and when I specify the path manually, fedpkg crashes.

Version-Release number of selected component (if applicable):
fedpkg-0.5.1.4-5.fc14.noarch

How reproducible:
always

Steps to Reproduce:
$ fedpkg clone thunar-vfs
Cloning into thunar-vfs...
remote: Counting objects: 3, done.
remote: Compressing objects: 100% (2/2), done.
remote: Total 3 (delta 0), reused 0 (delta 0)
Receiving objects: 100% (3/3), done.
$ cd thunar-vfs/
$ ls
sources
$ git branch
* master

Actual results:
$ fedpkg import /home/chris/Desktop/thunar-vfs-1.1.1-1.fc15.src.rpm 
Traceback (most recent call last):
  File "/usr/bin/fedpkg", line 1086, in <module>
    args.command(args)
  File "/usr/bin/fedpkg", line 491, in import_srpm
    mymodule = pyfedpkg.PackageModule(args.path)
  File "/usr/lib/python2.7/site-packages/pyfedpkg/__init__.py", line 938, in __init__
    self.distval = self._findmasterbranch()
  File "/usr/lib/python2.7/site-packages/pyfedpkg/__init__.py", line 886, in _findmasterbranch
    return(int(fedoras[-1].strip('f')) + 1)
IndexError: list index out of range

Expected results:
bash completion should work and the package should be imported just fine.

Additional info:
(10:49:18) ricky: It looks like the fedpkg code requires that there be at least one Fedora branch, which is a bug
(10:50:01) stick [~stick.net] hat den Raum betreten.
(10:50:40) ricky: And for the master branch, it uses --define fedora fcXX where XX is the highest existing Fedora branch
(10:51:05) cwickert: I see
(10:51:26) cwickert: so I'll import it manually and file a bug
(10:51:29) ricky: I wonder what reasonable behavior would be for EPEL-only packages though.
