Description of problem:
I used ImageMagick V6.7 "convert" on a large picture (identify -> "picture.tif TIFF 57086x57618 57086x57618+0+0 8-bit Grayscale DirectClass 2.4045GB 0.000u 0:00.160"). I have 16 GB RAM in my PC. I think it is a combination of convert and the fedora-shell (maybe the buffer or cache-mechanism)? It also occurs on the GraphicsMagick equivalent. But only in Fedora-shell. On Ubuntu 12.04 shell the behaviour is a little different: The convert-process in GraphicsMagick worked, but with resize and convert I stopped it after 6 hours.

Version-Release number of selected component:
ImageMagick-6.7.5.6-4.fc17

Additional info:
libreport version: 2.0.16
abrt_version:   2.0.16
backtrace_rating: 4
cmdline:        convert 'xFab Wafer.tif' -resize 2% 'xFab Wafer.klein.bmp'
crash_function: ImportGrayQuantum
kernel:         3.6.3-1.fc17.x86_64
