Description of problem:
I'm trying to update F-13 manually, via yum.  I tried to run the command "yum update" as root.  All of the packages were downloaded properly, but when yum attempted to run the transaction, an error occurred.  Subsequent calls to yum update elicit a different error, when yum looks for the pidfile.

Version-Release number of selected component (if applicable):
yum-3.2.27-4.fc13.noarch


How reproducible:
All attempts to run a yum update ("sudo yum update" or "su -c 'yum update'" in the terminal) seem to elicit this problem

Steps to Reproduce:
1. Enter yum update into the terminal as root
2. Get sqlite error
3. Run yum update again, get pidfile error

  
Actual results:
2 separate, repeatable Python tracebacks

Expected results:
My packages get updated

Additional info:
The following is the traceback that appears on the terminal:

$ sudo yum update

Subsequent yum updates seem to elicit a different traceback:

$ sudo yum update

    if (not os.path.exists("/proc/%d/status" % pid) or

For the record, there is no /var/run/yum.pid file, and I don't see any packagekit or yum processes in ps before I call yum (I have gnome-packagekit disabled).
