wide SVG file that caused the SEGV (346.35 KB, image/svg+xml)
2011-03-09 19:55 UTC, Martin Olsson 		Details

Description Martin Olsson 2011-03-09 19:54:22 UTC 
I'm using ubuntu lucid lynx (10.04) which means I got eog "2.30.0-0ubuntu1".

I was playing around with generated SVG graphs showing the #includes in firefox when suddenly eog crashed. I think it's because the SVG happened to get really wide.

repro:
1. load SVG file
2. zoom a lot
3. scroll all the way to the left and then all the way to the right

Here is the backtrace for the SEGV:

better repro steps:
1. click the ZOOM button on the toolbar 7 times to make the zoom level 100%
2. double click the eog window caption bar to maximize its window
3. scroll all the way to the left and then all the way to the right

These steps hit the crash 100% of the time for me. It also works if I switch the order of steps 2 and 3.

My screen res, should be relevant, is 1680x1050.

Yes, there's likely two problems involved here.

First, you are right about the size. eog has problems drawing larger raster images (bug 163090). The limit is ~32k px in any direction. For 100% zoom we also used a rasterized variant of displayed SVGs in 2.32. The current development series 2.91.x (the upcoming 3.0) also renders natively at 100% so this not a limitation anymore. 

Second, 2.32.0 had a known regression regarding on how far it let you scroll your image (bug 631710). Precisely it would let you scroll too far by not setting the adjustment values of the scrollbars correctly, rendering garbage once you scrolled out of the image area. This apparently even causes a crash in the rendering code with your image. Yet, this has been fixed in 2.32.1 where I cannot reproduce this anymore while I can reproduce it with 2.32.0.
