Comment 3 for bug 444527

gattrib/src/gtkitementry.c is the offending file.

This is the fix applied to gEDA 1.6.0 (remove the offending file and use a different widget):
http://git.gpleda.org/?p=gaf.git;a=commitdiff;h=78da20ca286eb2f6e518c64dca94b888fc8c19af

The diff won't apply directly, but it should only be build system changes which don't apply. They won't be needed for the 1.4.x series.

My preferred fix would be to see if we can sneak a 1.6.0 package into Karmic ;)

(That way we're all running the same tested code, not applying huge patches to unmaintained upstream versions).
