** Description changed:

  There is definitely a problem with Nautilus and only with Nautilus. No
  need to make jasper shoulder the GNOME responsibility.
  
  On Ubuntu Trusty 14.04 LTS I have installed both Marlin and Nautilus /
  Nemo File Managers.
  
  Marlin has no problem previewing JPEG 2000 thumbnails in .j2k and .jp2
  format.
  
  However Nautilus [3.10] / Nemo (both) are constantly crashing. e.g.
  
  nautilus crashed with SIGSEGV in jpc_qmfb_join_colgrp()
  
  On the command line running jasper is working fine too (Cevennes2.jpg is
  coming right from the official website)
  
  http://www.openjpeg.org/index.php?menu=samples
  
  $ jasper --input Cevennes2.jp2 --output Cevennes2-bis.bmp --output-
  format bmp
  
  When will Nautilus behave appropriately for JPEG 2000 thumnbails ? This
  is dating back for years ...
