const char *pathentered is out of bounds when it runs out the function.
Try to chage:
gtk_entry_get_text(GTK_ENTRY (widget))
.. with ...
gtk_editable_get_chars(GTK_EDITABLE(widget), 0, -1)
It returns an allocated buffer - you should remember to free it - and
will not get out of bounds when this function ends.
