Wrong parsing of steam registry
Since commit d739a372, steam apps are searched in the registry. On my sistem (debian unstable, steam client installed by .deb package), the registry is located as expected in .steam
However, the line
private const string[] APPS_REGISTRY_PATH = { "Registry", "HKCU", "Software", "Valve", "Steam", "Apps" };
in steam-uri-source.vala
gives a prolem, since the correct class in the registry is "apps" with lowercase A. Ths causes no steam games to show up. Modifying the string all works as normal.
I don't know if this behaviour is specific to my system, maybe a non case-specific general solution might be the best way to go.
