YUMng throws exception on RHEL4

[davisj <[email protected]…>]

With yum 2.4.3 on a rhel4 client, python 2.3. YUMng throws the following exception.

Reading Local RPMDB

The value of pkg, dest[pname] and data at this point in the code are "('kernel', 'i686', '0', '2.6.9', '89.0.20.EL')", "{'i686': ('0', '2.6.9', '89.EL')}", and "[('i686', ('0', '2.6.9', '89.0.20.EL'))]" respectively.

The following patch against trunk seems to fix the issue though I'm not certain it wouldn't introduce other problems.

This bug is now superceded by bug # 935 as the YUMng code has been mostly rewritten.

I'll leave this open as this does apply to the code attached to 935.

I think that we should be ok with the new yum24 driver. It seems to have appropriate guards.
