Status changed to 'Confirmed' because the bug affects multiple users.

I got this error when doing a dist-upgrade from 14.4 LTS to the new 16.04

Got this error too, tried to solve it forcing uninstallation with dpkg -r --force-depends shared-mime-info and reinstallation, same error. Tried to manually remove every file/folder of this package using locate [package], tried to edit .postinst and .postrm files with exit 1 or 0 both, nothing solved the error.

Found a way to fix it, installed the latest libxml from sources and shared-mime-info configured as it should, but now when I log in, the shared-mime-info database.real crash.
