After updating some gnome libs i have error
./gens: symbol lookup error: /usr/local/lib/libgio-2.0.so.0: undefined symbol: g_main_context_get_thread_default
after choose File->Open ROM, but others functions work well.
I tried build Gens from source but error found again.
Distr: Slackware 13.0
glib-2.21.6
gtk+-2.17.11
But now i falled back to glib-2.18.4 and all works! May be it's glib bug?
