Description David Cantrell 2018-01-12 19:12:51 UTC 
Coverity as invoked by the Errata Tool found some legitimate bugs that we should fix.  I have patches for them, but in order to push my change and do a build, I need a Bugzilla bug with acks, so I'm filing this now.

The fixes are all in src/pydisk.c and involve adding guards around two variables.

Please ack me.
