Comment 1 for bug 1480419

Which installer did you use for Inkscape 0.91 - 32bit or 64bit?

To allow further investigation of the reported issue, please attach a test case (Inkscape SVG file, or one of the pixel art images which produce the reported crash), and provide details about
- bitmap image import settings
- settings for 'Trace Bitmap' (or 'Trace Pixel Art') [1]

--
[1] it is not clear from the description which trace method you used - 'pixel art' and 'large' are somewhat opposite terms.
