Description Raphaël Quinet 2001-06-06 17:00:36 UTC 
The following message was posted to the gimp-developers mailing list
by Avi Bercovich <avi@mediamatic.nl>:
> 
> Colour conversion of the xcf file at

I tried to convert that file (see next attachment) to indexed mode using
gimp-1.2.1 running under Solaris 2.6 (I assume that Avi was using Linux
2.4).  I selected 31 colours, no dithering.  The Gimp crashed with the
following error message:

Gimp-ERROR **: file convert.c: line 2345 (median_cut_rgb): assertion
failed: (b2->Gmax >= b2->Gmin)
aborting...
gimp terminated: Abort

Comment 2 Adam D. Moss 2001-06-06 21:23:26 UTC 
Fixed in local tree but fix is 1.3.x-specific.  Will
try to find time for workaround in 1.2.x tree.
Comment 3 Garry R. Osgood 2001-06-07 02:50:44 UTC 
This report confirms #52264, the reporter of which furnished a stack
trace with the same assert message reported  by Avi to the news list.
