KeepassX installs iteself as default app for all MIME types

[rob]

Seems that in Kubuntu 16.04 beta, the KeepassX package installs itself as the default application to open all mime types. So, if I download a .deb file, the system will open it with KeepassX. Clicking on a .log file will open KeepassX. Etc. Any file type that doesn't have a specifically defined application association will open KeepassX. Obviously, not particularly useful behaviour.
