When using the text tool in GIMP 1.3, after writing some text, several
times I have accidentally typed a huge number in the font size field of the
text tool dialog. While GIMP automatically scales the number down to 8192
(px), it still goes on it's way trying to render my text in that huge font.
Before I even notice, I have switched to another window and the system has
gone unresponsive and GIMP starts creating a _huge_ swap file.

In some cases I have lost my work this way. The Gnome HIG says to forgive
the user. This is a severe breach of that principle. I think if the number
is exessively large it should warn me, or perhaps there should be a
"Cancel" button or another way to recover my work.
