clist (gtk-0.99.3) problem

[Roman Pozlevich <roma botik ru>]

Hello!

Can somebody explain me why attached program crashes EVERY time I made
second click on "refresh" button.  The error message is 

"** ERROR **: BadPixmap (invalid Pixmap parameter)"

It NEVER crashes if the number of rows is less than 100.

That happens with both GTK-0.99.2 and GTK-0.99.3
