Removable devices are not detected anymore

[Sandro Mani]

Hi,

I noticed today that my rawhide system stopped detecting removable 
devices. When I plug in i.e. a USB stick, dmesg and udevadm monitor show 
all the usual stuff, but dbus-monitor remains silent. Neither the KDE 
device notifier (or dolphin) nor the gnome file dialog pick up the 
device. setenforce 0 does not help. Manually mounting works. Any ideas 
where I should hunt?

Thanks,
Sandro
