[Bug 555238] Re: nautilus crashed with SIGSEGV in jpc_qmfb_join_colgrp()

[Antonio19]

My 2 cents on this "bug" after experementing 3 versions of OpenJPEG
release. [http://www.openjpeg.org/]

The official version released in any Debian or Ubuntu distribution is
libopenjpeg2_1.3+dfsg [...]. This package is build from version 1.3 of
the source code from the Google Code project
http://code.google.com/p/openjpeg/

Since then they have released version 1.4, 1.5, 1.5.1 and 2.0.0. My own
experience for having installed version 1.3, 1.5 and 2.0.0 is that the
compressed images j2k are not compatible between versions. You end up
with a crash in the jasper package. See their Canadian website @
http://www.ece.uvic.ca/~frodo/jasper/

However for some reason when another version is installed jasper crashed
and following this crash Nautilus or Nemo crash as well.

Aside from the jasper / nautilus - nemo trouble between different
OpenPEG versions, GIMP or GPicView had no problem opening j2k images
from other versions of OpenJPEG.

When recompressing the source images to j2k with the new version I idn't
get any crash. However the thumbnail will not show up on some images ...
all thumbnails only appear with the official v1.3 version still part of
the latest distibutions from Ubuntu or Debian.

See their website for  experimenting on samples
