[PATCH] Fixed some small memory leaks

[Lubomir I. Ivanov]

From: "Lubomir I. Ivanov" <neolit123 at gmail.com>

Looks like a GtkEntryCompletion object created with
gtk_entry_completion_new() should be unreferenced after usage
(e.g. post gtk_entry_set_completion())

In info.c:get_combo_box_entry_text(), moved the free(..) line outside,
so that we can free regardless.
