createrepo-0.4.6 creates defective metadata if filesystem is full

Hi,

just wanted to let you know, that in case of a full filesystem,
createrepo creates defective repodata without any error indication,
finally leading to segfaults in yum.

Here's a related backtrace:

I haven't investigated deeply, since the whole process of generating
such defective output should be suppressed somehow (by removing the
offending files in the FS full case), and let yum simply bail out instead 
of just crash, when accessing such a repo. 

Well, I know, this message is missing the corrective patch, but "doing
the whole druidic festival around the tree thing"¹ has higher precedence 
ATM..
