I did a yum update on my f10 x86-64 box at work today and discovered a minor bug in the packaging:

Transaction Check Error:
file /usr/lib64/libmarblewidget.so.4 conflicts between attempted installs of kdeedu-libs-4.1.2-2.fc10.x86_64 and kdeedu-marble-4.2.0-7.fc10.x86_64

A google for this found only one mention on a fedora forum, but it was in German.  Fortunately the Google translation was clean enough for me to decipher the solution.  The kde EDU libs are apparently needed by digikam-libs.  Removing this package first and then doing the update will allow the update to complete successfully.  You can then install digikam-libs again without error.

The forum messages suggest the bug has not been reported to bugzilla.redhat.com so I attempted to make the report today. Unfortunately I'd made a login on that site long ago but don't seem to have password handy.  Asking bugzilla to contact me so I could update the password didn't seem to work either.  So I wan't able to report the problem.

Update:  2009-02-26

I was able to login to bugzilla and file the report.  I did additional testing and found the I could not reinstall digikam-libs after the update completed.  That's not important to me since I don't use that library on that system, but I noted it in the bug report.
