Yes. And I use GTK+ over a remote connection constantly.

See the code around line 264 of gdkimage.c. The only reliable
way of detecting the remote display case is to catch the
failure when you first try to create a shared image, so
this is what GDK does.

You can also run your program with the --no-xshm flag, but
it shouldn't be necessary.
