[Bug 427100] Re: JPEG2000 thumbnail causes browser to crash

[LaunchpadLoginDefectReport]

Still failing intermittently on 14.04 LTS updated to current as of two
days ago.  I have directories full of images such as

http://chroniclingamerica.loc.gov/lccn/sn88084272/1911-07-22/ed-1/seq-24.jp2

which are high-resolution scans of old newspapers from the Library of
Congress.

When it works correctly, the file icon shows a clock "wait" icon while a
thumbnail is being generated from the 9MB greyscale image.  Doing
something with the folder during thumbnail generation breaks something,
and the file browser then crashes whenever the folder is opened.

The Nautilus crash dump should have already been automatically uploaded
to Ubuntu.

Title:
  JPEG2000 thumbnail causes browser to crash

Status in jasper package in Ubuntu:
  Confirmed
Status in nautilus package in Ubuntu:
  Invalid

Bug description:
  Binary package hint: nautilus

  Attached file was generated by the Meerkat Second Life viewer.

  THe file is a "texture" file in JPEG2000 format.  The file reads
  properly with the Meerkat viewer (Linux and Windows) and with
  IrfanView (Windows). Nautilus correctly lists this file unless the
  thumbnail function is enabled.

  With thumbnail enabled Nautilus reads about 70% of the JPEG2000 files
  then crashes. No crash report is generated.

  However the SECOND time that the file is listed the thumbnail works!

  This is a problem since there are several hundred of these files in a
  directory.

  I have been unable to find a validation tool for JPEG2000 to rule out
  format errors in the file itself.

  I can supply many more examples of these files if it would help trace
  the problem!
