As already said, I think it is not a Geany but a GTK+ bug.
BTW, https://bugzilla.redhat.com/show_bug.cgi?id=603781

This bug (that isn't fedora-specific) happens sometimes when the GTK+
file chooser gets updated. Since Geany never destroys its filechooser,
it makes it more vulnerable to this bug than some other software.
