Description of problem:

Cannot remove /var/cache/yum/i386/14/Dropbox/primary.xml.gz.sqlite. I need to remove this file to perform a Yum Clean all and Yum Update. 

Under /var/cache/yum/i386/14/Dropbox/, I have the following output...

ls: cannot access primary.xml.gz.sqlite: Input/output error
total 12
drwxr-xr-x  3 root 4096 Mar 16 09:25 .
drwxr-xr-x. 5 root 4096 Mar 16 09:25 ..
drwxr-xr-x  2 root 4096 Mar  7 13:57 packages
-?????????? ? ?       ?            ? primary.xml.gz.sqlite

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

N/A

How reproducible:

* Install Dropbox, run as a non-root user

* Try to do a Yum Clean All or Yum Update and it will blow up.

Expected results:

Primary.xml.gz.sqlite shouldn't have question marks?
