search for a word for which a defintion is not found -> a dialog is popped up. When you close the dialog window->word is freed, when you search again window->word is freed again -> BOOM :)

I don't think there is any need to free when closing the dialog so I took that free() out. (the alternative is to set window->word = NULL after the free).


Along the way I also noticed another buglet: if you press enter when the definition entry is empty "" is looked up in the dictionary and the title is set to "dictionary - ". This is because gtk_entry_get_text never returns NULL so you need to check that *text != '\0'.
