Package: gok
Version: 0.11.3-2

When running, gok prints out the following output and terminates:
/dev/js0: No such file or directory
0 event types available
login mode = false
Word prediction dictionary contains a total of 3000 words
gok: art_render_gradient.c:337: art_render_gradient_linear_render_8:
Assertion (stops[ix-1].offset <= offset_fraction + 1e-6) ||
((stops[ix].offset > (1.0 - 1e-6)) && (offset_fraction < 1e-6 ))'
failed.
Aborted

(My system is fully apt-get upgrade'd.)

 Do you still get this problem with newer versions of gok?

   Thanks,

 I didn't get any reply and your report is very old, hence I'm closing
 it.  If you still experience this bug with the current gok packages
 from unstable, please reopen this bug (or mail me).

   Bye,

I found the very same bug using Trinity Desktop in Ubuntu (but not in Debian).
When opening /usr/share/applications, konqueror aborts with this:
konqueror: art_render_gradient.c:337: art_render_gradient_linear_render_8: Assertion `(stops[ix-1].offset <= offset_fraction + 1e-6) || ((stops[ix].offset > (1.0 - 1e-6)) && (offset_fraction < 1e-6 ))' failed.

It seems to happen when reading softwarecenter.desktop and trying to open
/usr/share/icons/hicolor/16x16/apps/softwarecenter.svg.

It's related to this bug: http://bugzilla.gnome.org/155472.
The patch suggested at this time (2004!) by Brian Tarricone was never applied
to libart but I think it should have been.
Please consider including it in Debian.

I'm not forwarding this bug to bugzilla.gnome.org.
They didn't applied this patch in 2004 and they closed all bugs relating to
libart-lgpl, in August 2011, because it's unmaintained.

Neither am I opening a bug in Ubuntu since I think it's not 'Ubuntu-specific'.
The bug doesn't happen in Debian but it is in Debian's libart_lgpl.

(I made another bug report at http://bugs.pearsoncomputing.net/554.)
(Patch attached)
