Yet Another GtkText Bug...

[Thomas Mailund Jensen <mailund daimi aau dk>]

Here's another program that crashes the text widget...I don't know if
it's related to the other bugs...

Run the program, typein "foobar" (or something else with more than 3
lettes), and then press F1.

It'll then crash with:

** ERROR **: file gtktext.c: line 4183 (find_line_params): "lp.end.property"
