Midori does not start when Windows asks it to (0.5.11)

[Oleg Dozorov]

As already said in h1, Windows does not open the clicked hyperlinks and does not perform other web-related actions in Midori 0.5.5, when Midori is a default browser (BTW, after this I already have set Firefox as default browser, how can I get Midori as default back (:? )
I don't have to say anything moar about this, even though I want to ):..

(Here goes the about:version info for my case

UPD: after installing Midori 0.5.11, the problem changes a bit: now every time Windows calls a default browser, another browser (Firefox, for example) start up, but after starting it says that it is not a default browser.. This looks even more strange.
My About:Config is now {
