I think I emerged a new version of python. After that, my startbar stopped working. I tried anything (re-emerged desklet-core and stuff) when I finally found out that somehow the xdg stuff must have got broken. pyxdg-0.5 was still installed, but not available in python any more. I don't know if this is a gentoo problem or not, and can be addressed by portage somehow. But I wanted to notify someone at least :) Reproducible: Didn't try Steps to Reproduce: would be hard to reproduce because the problems started with emerging a new python version.
Lars: Did you run `/usr/sbin/python-updater` as the python post-install message told you? If you did, provide `emerge info` please, otherwise I guess this bug is invalid.
I'm pretty sure I did not, I did not even realize that python was updated in the first place (was a dependendy). I'll mark this invalid because of RTFM, then :) Of course this ebuild behaviour is not nice, but this is a general problem, as many ebuilds show messages like this that can very easily be missed when updating >200 packages for emerge -u world or something. thanks, anyway, script is running and re-installing packages right now.
