Btw, you should do:

new Gee.HashMap<string,string>(GLib.str_hash, GLib.str_equal,
GLib.str_equal);

Without specifying comparision/hash functions for the hashmap the direct
hash/comparision functions are used which simply compare pointers. For
string keys you don't want to compare pointers unless they're quarks or
something like that (but then you would use GQuark as key I guess).

The specific problem here is, that the hashmap internally strdups your
string keys which generates a new pointer. And then the key changes ;)
