Comment 2 shmuel siegel 2010-02-24 11:53:10 UTC 
I don't know why this is reported as Fedora 12. This comes from trying to install the alpha rc2 of fedora 13.
Comment 3 James Laska 2010-02-24 13:26:26 UTC 
I get the same thing when attempting to upgrade from a minimal F-12 system using F-13-Alpha-RC2.  I also see a failure while attempting to present the error handling dialog.  I've opened that against python-meh (see bug#567963)

13:10:35 Please manually connect your vnc client to test1247.test.redhat.com:1 (10.10.10.247) to begin the install.
Press <enter> for a shell

Comment 6 James Laska 2010-02-24 17:58:53 UTC 
While upgrades are not listed in the F-13-Alpha release criteria (https://fedoraproject.org/wiki/Fedora_13_Alpha_Release_Criteria), I suspect many people will attempt upgrades.  Adding keyword CommonBugs so adamw or I can document this issue for F-13-Alpha testers.
Comment 7 shmuel siegel 2010-02-24 18:33:55 UTC 
In my case, this was very serious and should be avoided by alpha testers who don't have a throw away configuration. Upon rebooting, I had a configuration which wouldn't run. It has a very bad mixture of f12 and f13 components, over 300 dupes including kernel-PAE, fedora-release, gcc and cpp. Package-cleanup wants to delete too much so this is going to have to be cleaned by hand. I would strongly advise people to avoid upgrading until this is fixed.
Comment 8 Chris Lumens 2010-02-24 19:33:51 UTC 
Looking at:

http://git.fedorahosted.org/git/?p=anaconda.git;a=blob;f=yuminstall.py;hb=HEAD#l233

You see that this only occurs on a couple cases in the RPM callback - all errors.  In testing, I hit this case a couple times during one upgrade.  The first time during package installation, h was a tuple like we're expecting.  The second time it happened is post-installation, I believe after rpm.RPM_CALLBACK_UNINST_START/STOP has been seen in the above case.  This second time through, h is the string "cyrus-sasl".

Any idea what's going on here?  Shouldn't we be getting the same type as argument in all cases?
Comment 9 James Antill 2010-02-24 21:10:26 UTC 
Chris, this is "normal" for rpm, we have a bunch of code in yum to handle it now Eg.:

Sigh, okay.  Thanks for the pointer.
