I use ImageMagick 6.6.8-5 (Gentoo)
When I tried to convert from djvu to png, I got a segmentation fault.
# convert book1.djvu 1.%d.png
My USE flags are "media-gfx/imagemagick png jpeg tiff djvu fontconfig truetype autotrace gs jbig jpeg2k lqr raw svg wmf xml"
I tried to change USE flags to djvu and png only, but got the same result.
