Description j.gnome 2005-06-19 15:20:58 UTC 
Windows XP, 1.5.2-rc1

I have an Excel file that says "x_order_2: colinear!" in the console. It
probably has something to do with graphs. I can't attach the file here, but I
can send it by email.
Comment 1 j.gnome 2005-06-19 15:28:38 UTC 
Possibly related: the about dialog says

colinear!
colinear!
x_order_2: colinear!
x_order_2: colinear!

etc. 
(I already reported the about dialog stuff in bug 301933, probably wrong bug)
Comment 2 Jean Bréfort 2005-06-20 07:02:56 UTC 
I'd be interested by a sample file. Aniway, these warnings come from libart and
are not harmful.
Comment 3 Emmanuel Pacaud 2005-06-20 08:04:31 UTC 
Those warnings come from numerical stability of libart routines. 

Looking at comments in libart sources, it seems a solution could be to perturb
paths before doing something with them. This is already the case for polygon
rendering, so may be we should do the same for lines.
Comment 4 Emmanuel Pacaud 2005-07-05 09:12:52 UTC 
For the record, I've tried to perturb paths before rendering, but it does not help.
Comment 5 Emmanuel Pacaud 2005-08-17 15:08:23 UTC 
These warnings are harmless. I'm closing this bug.
Comment 6 j.gnome 2005-10-20 16:07:45 UTC 
Does this have something to do with bug 132558?

Is the "art_svp_writer_rewind_new" thingie from bug 132558 comment 3 somehow
relevant?
