Strange things most likely occur after attempting to free the const
string in entry_changed_cb()

    g_free(prefix);

which was fine if prefix was NULL initially.  You can use -Wwrite-strings
to catch that.  Unforutnately, passing constant strings as various
user-data-kind arguments or to g_hash_table_insets() then produces
warnings too.

Also learn to use valgrind; it would show you this problem immediately.
