Description david gowers 2005-09-27 14:03:28 UTC 
steps to reproduce:

* new image
* select a largish (easily visible) brush
* choose convolve tool, set to blur.
* try to paint across the edge of the image -> crash.

The most intuitive behaviour would be to treat all pixels past the image border
as being the same color as the last pixel inside the image border (like what
several plugins call 'smear' mode)
Comment 1 Sven Neumann 2005-09-27 15:33:20 UTC 
Crashes in color_region(), called from convolve_paint().
Comment 2 Michael Natterer 2005-10-29 00:58:29 UTC 
Fixed in CVS:

	* app/paint/gimpconvolve.c (gimp_convolve_motion): allocate both
	oversize buffers with the right size, instead of one twice with
	the wrong size. Was broken since porting to pixel_region_init_data().
	Spotted by Seth Burgess. Fixes bug #317340.
