Attached traceback automatically from anaconda.

Numerous attempts to install FC10 on this system always result
in this failure from anaconda.  I have tried directly from
DVD .iso, from network .iso, network via URL to a mirror site,
blows up the same way every time.

This system was previously running FC9 without issue.  I tried to
upgrade and that resulted in hangs, lockups and finally the inability
to complete the install due to a missing dblib of some sort which
RPM and yum needed to finish the install.

So, I have gone back to trying to install FC10 fresh-- wiped
the disk-- yet I continue to encounter these python dumps from
anaconda.

Very frusterating.  This is not what I have come to expect from the
Fedora project.

Traceback (most recent call first):
  File "/usr/lib/python2.5/site-packages/yum/sqlitesack.py", line 237, in returnPrco
    if isinstance(self.prco[prcotype], tuple):

TypeError: _share_data() takes exactly 1 argument (2 given)

...awesome, not only is _share_data() not called on that line, but AFAICS it isn't called with two arguments anywhere in that file.
 Did you check the media?
