This doesn't look to be a bug with device-automounter, rather one with Solid. Furthermore, I'm confused how you're able to make device-automounter forget about devices via the device notifier plasmoid. The two are not connected in any way. Unless Ubuntu is doing some magic patching that never gets back to me. Regardless, this backtrace is clearly from the hal backend of solid.
Well theres a mount plasmoid in the sys tray,and when you right click on it theres a option at the last which says " Forget Device " and there are check boxes over various partitions and when you click on all of them at once and click on forget devices solid crashes. Im unsure if there is any patching of sorts done to this plasmoid,but ill get this confirmed
