[snap] kwallet not detected as password store

[Olivier Tilloy]

(initially reported at https://forum.snapcraft.io/t/call-for-testing-chromium-browser-deb-to-snap-transition/11772/8)

« The test command¹ you use to detect backend:

dbus-send --session --dest=org.freedesktop.secrets /org/freedesktop/secrets --print-reply org.freedesktop.DBus.Properties.GetAll string:'org.freedesktop.Secret.Service' >/dev/null 2>&1

fails o my system (Ubuntu 19.04 + KDE session + kwallet) saying that nothing provides org.freedesktop.Secret.Service and chromium fallbacks to plain backend (losing my passwords). When I add --password-store=kwallet to desktop file command it works correctly.

So current approach for backed detection is broken in my case (maybe in general for kwallet). Maybe it’s possible to test also kwallet equivalent of that command however I don’t know what i should be. »

I can reliably reproduce the problem in a Kubuntu 18.04.3 VM.

The following test should do the trick:

dbus-send --session --dest=org.kde.kwalletd5 /modules/kwalletd5 --print-reply org.freedesktop.DBus.Properties.GetAll string:'org.kde.KWallet'
