 depcheck is crashing almost every time (116 crashes in 118 runs) on fc19.
 The common crash seems to look like this [http://autoqa-
 stg.fedoraproject.org/results/242568-autotest/virt10.qa/debug/client.0.DEBUG
 example crash log]

 Traceback:
 {{{

 }}}

 On the bright side, it seems to not happen on fc18 clients, so we could
 work around it in the short term by limiting depcheck scheduling to fc18
 clients but that's only going to work for so long.

 Figure out how difficult it will be to fix this depcheck crash and whether
 or not it's worth fixing in the short term.
