STEPS: JDK1.2.1 build "K" both Win32/Solaris

1. launch "SwingSet" on demo/jfc/SwingSet
2. "Choosers->File Chooser"
3. select "cow.gif"

Image is not displayed in thumbnail, but produce exception.

java.lang.IllegalArgumentException: Width (90) and height (-1) must be > 0

<..... CUT .....>

From stack trace, it looks like loadImage tried to shrink the size of "cow.gif" -- large gif image -- to thumbnail.

In JFileChooser, the exception should be caught. Preferred way is instead of output the exception, but show some warning in file chooser thumbnail area. Say, "image cannot fit".
