[patch] this is a pyparted patch for 429185

[Joel Andres Granados <jgranado redhat com>]

I'm posting the patch here because I don't know where pyparted discussion list lives :)

You can find the patch at https://bugzilla.redhat.com/attachment.cgi?id=305028

pyparted needs to search the valid partitions before it returns anything in the py_ped_disk_next_partition function.  With this patch we can now save anaconda tracebacks to usb keys.  I build pyparted but didn't test the patch extensively.
Comments are greatly appreciated.

PS: For the lazy ones, I'm attaching the patch also. :)
