Conflicting yum repositories

[Trey Sizemore <trey fastmail fm>]

I have the following repositories setup for yum, and I'm getting package
conflicts during updates due to version mismatches:

atrpms
atrpms-bleeding
atrpms-testing
dag
dries
flash
freshrpms
jpackage-fedora
jpackage-generic
kde-redhat
kde-redhat-all
newrpms

Are there repositories listed above which are known to conflict?

Thanks.
