Errors in gtk+-1.1.7

[Roland Bock <rbock eudoxos de>]

I think I detected some errors in gtk+-1.1.7 using testgtk.

1. trying the "layout" button and closing it via window manager (fvwm2
if this is of interest) causes the whole program to freeze completly. No
graphics are updated, no mouse click is heeded. Ctrl-C leads to the
typical message, but does not stop the program when used only once.

2. using the "shapes" button kills the program which is just able to cry
out:

Gtk-CRITICAL **: file gtkpixmap.c: line 89 (gtk_pixmap_new): assertion
`val != NULL' failed.

Gtk-CRITICAL **: file gtkfixed.c: line 134 (gtk_fixed_put): assertion
`widget != NULL' failed.

Gtk-CRITICAL **: file gtkwidget.c: line 1396 (gtk_widget_show):
assertion `widget != NULL' failed.
Gdk-Message: 
** ERROR **: sigsegv caught

3. Playing with text:
Inserting random text and adding text manually lead to random crashes or
freezes. I guess that because you add random text, the error is not
reproducable. What I did:
Adding some random text (about 10 times), adding some newlines (10-30)
somewhere in the text, continue with random text. After another 2 to 30
random texts, the result is one of the three following:
a) The program crashes with
Gdk-Message: 
** ERROR **: sigsegv caught
b) the program freezes and nothing but Ctrl-C work any more.
c) the program freezes with "add random" still active and continues to
add text forever (unwilling to die of cause a)).
