Fontforge closes on 15th click on vertical scroll bar

Fontforge version (from help>about): 02:03 GMT 10-Nov-2007 (20071110)
From apt-cache policy fontforge: 0.0.20071110-1build2

Viewing a font when first opened, pixel outline size (under View menu) 24 pixels, anti-aliasing on. Scroll down by clicking the right-hand scroll bar; on the 15th click, Fontforge instantly closes.

With 48 pixel outline size, this closure occurs on the 44th click of the scroll bar. (Haven't tested this exhaustively)

This happens:

1. whether a charcter is highlighted or not
2. with both .ttf and .otf fonts from disparate sources

If you scroll via View>Go to, specifying a character name, a Unicode point (i.e. U+2077), or a Unicode block name (i.e. Georgian or Georgian Supplement), Fontforge scrolls correctly without exiting.

This sudden closure does not leave a sleeping or zombie process.

Addendum #1: The bug as reported refers to having the display not quite maximized. With the display maximized and 24-pixel outlines, there are 40 characters across the width of the display, and the sudden closure is on the 14th click.

24-pixel outlines, 39 characters per row (not maximized), the 14th screen (last before crash) has U+2220 in upper left

24-pixel outlines, 40 characters per row (maximized), the 13th screen (last before crash) has U+2080 in upper left corner.

48-pixel outlines, 20 chars per row, (not maximized), the 43rd screen (last before crash) has U+2198 in upper left.
