I found out what's going on. I was using a Qt nightly build. It seems mailto handler is broken in Qt version atm. I installed GTK nightly build now and mailto works. Now I installed latest Qt build and mailto is broken again. Lastly back to GTK and it works again.
This is a real shame coz Qt build is significantly faster for me.
I'll file a bug report if it hasn't been already.
