Description of problem:

While trying to build a an ISO, here is what I get:

Traceback (most recent call last):
  File "/usr/bin/livecd-creator", line 237, in <module>
    sys.exit(main())
  File "/usr/bin/livecd-creator", line 218, in main
    creator.install()
  File "/usr/lib/python2.7/site-packages/imgcreate/creator.py", line 655, in install
    ayum.runInstall()
  File "/usr/lib/python2.7/site-packages/imgcreate/yuminst.py", line 221, in runInstall
    raise CreatorError("Dependency check failed : %s" % "\n".join([dep[0] for dep in deps]))
TypeError: sequence item 0: expected string, tuple found


The reason is this line:
CreatorError("Dependency check failed : %s" % "\n".join([dep[0] for dep in deps]))

And it breaks because:

deps = [(('mariadb-server', '1:5.5.31', '6.fc20'), ('systemd-units', ''), 0, 0, None)]

The list items are expected to be strings, rather than tuples, iiuc.


Version-Release number of selected component (if applicable):

livecd-tools-19.5-1.fc19.x86_64

How reproducible:

Always.


Steps to Reproduce:
1. Download kickstart file from https://gist.github.com/amitsaha/5973063/raw/e5b24da0af21179dd78636174e0798fbb6519763/fedora_20_livedvd_scientific.ks
2. Place it in a clone of spin-kickstarts dir
3. livecd-creator <above ks file>

Actual results:

Crash as above.

Expected results:

Error out saying "Dependency check failed". Do not crash with a TypeError.
