To the best of my knowledge this error occurs because of a change in something that fontforge is dependent upon not because of a change in fontforge itself the same error occurs if one puts an older version of fontforge on a newer Linux. I got the same error when I upgrade unbuntu-9.10 to ubuntu-10.04, and also when I tried running fontforge on PuppyLinux, both using a 2009 build. I thought briefly by using a newer build had solved this, but on checking the further it is still there - just that it a few case one can use these keys. The widgets for fontforge where written by George Williams himself which may make check dependencies a little harder. Of course saying this does not mean that changing the depends list will solve the problem but it is a good place to start.
