Comment 1 Behdad Esfahbod 2007-05-16 11:57:20 UTC

If you can reproduce this, can you see what the value of result is before the assert failing (pangolayout.c:3444)?

Comment 2 Behdad Esfahbod 2007-05-16 12:35:57 UTC

I committed a fix that I believe should fix this bug.  Please test.

        * pango/pango-layout.c (process_item): Make sure we find some break
        point even if overflowing the line.

Comment 3 Sebastien Bacher 2007-05-16 13:54:37 UTC

result = 2 and the patch fixes the crasch
