The problem is probably that the _get_text functions don't return a
dynamically allocated string, they return a pointer to their own internal
data. So you need to g_strdup the string you get back if you want to
modify the text widget (unless you finish with the string before any text
widget mods). And of course you should g_strdup if you want to modify the
string, and you should be sure you don't g_free the text widget's string. 

That's my guess.
