Hi, my name is Atanas Beloborodov, developer from Bulgaria [small country on east europe :)] and i use Geany for my everyday work, so i decide to help with development as i can.
Here is a small patch for main.c, that checks for GLib version and avoid call of g_thread_init() if GLlib version > 2.32 since this function is deprecated in GLib > 2.32
P.S.: Thanks to the SardemFF7 from irc channel who helped me.
