[Pkg-fonts-devel] Bug#656359: [Pkg-fonts-bugs] Bug#656359: Bug#656359: Segfault when pressing modifier/arrow keys if more than 4 points are selected

[john knightley <john.knightley@gmail.com>]

Dear Khaled 

the segmentation fault is somewhat erratic for example moving around the letter g does not crash but moving say a character at uf8000 does - in some cases starting a new font, making it full unicode  going to a higher point and simply pressing element is sufficient to crash. Even if somewhat difficult to describe there is indeed a serious problem here. I have one machine running ubuntu 9.10 which I have been doing all my fontforge work on because when I update to ubuntu 10.4 I noticed this bug, which has remained though I have updated to 10.10 . 

Over the past week I have been preparing to do a fontforge training session in Feb and I myself thought that install rather than updating to Maverick solved the problem because I only tested 'g' . 

Regards
John

I can't reproduce this with fontforge built from git master running
under Ubuntu 10.04.
