Sorry for the overdramatic subject, but this is important.
Within the next few days Python 2.6 will be imported into Rawhide. This means that EVERY single Python-based package in Rawhide will be broken, and that we'll need to slog our way through rebuilding it package by package. I'm going to forgo the customary list of packages this time since they number in the hundreds. You can see them for yourself by using the following:
repoquery --disablerepo=* --enablerepo={development,rawhide} \ --whatrequires "python(abi)" | sort | less
Good luck, and godspeed.
