Since libqtkeychain1 is built without libsecret, applications depending
on libqt5keychain1 fail to load passwords on Gnome-based systems now.
For example, the ownCloud client asks for the password on startup (see
https://github.com/frankosterfeld/qtkeychain/issues/99). Installing
libgnome-keyring is not an option since it is replaced by libsecret
(https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=892359).
