RPM package read errors with Smart 1.4.1

[Steve Morris]

Hi Keith,
     How do I work out what is causing the problem? I found that there 
were a whole heap of rpm and .part files in the packages directory which 
I removed and I also removed the cache file but it made no difference to 
the issue.
    I am using Mandriva 2011.0, and the issue I have is I get these 
message at the start of the process having issued the command smart 
update and it usually also occurs about 75% of the way through, which as 
far as I am aware during this process rpm doesn't play any part in what 
is being done. All this process is doing is updating smart's view of the 
repositories.
     The other thing I don't understand is that while this issue is 
impacting smart, there is no issue with the native Mandriva package 
managers.

regards,
Steve
