Description Matt T. Proud 2004-04-08 05:11:38 UTC 
Here are the two PDFs that have caused the trouble:
http://www.freedomhouse.org/research/mrr2004.pdf
http://www.freedomhouse.org/pdf_docs/research/freeworld/2003/map2003.pdf

1.) Have Mozilla-Firefox set to open *.pdf with gnome-pdf-viewer
2.) Open either of the previous documents, and have Firefox use gnome-pdf-viewer
to open them
3.) Open completion and opening, gnome-pdf-viewer will crash

Here are two associated stack/backtraces from the previous files:

Which version of gpdf is this?

It has to be the latest GPDF available to Gentoo, which I believe is 0.131.

I should emphasize that after more testing, it appears that this crash only
occurs with the PDFs mentioned in this report, not ones from other sites. (Strange)

As a side note, I tried to report the version in which this error happens, but
GPDF's bugzilla page does not have itself scripted to report the product
versions; I suggest adding this feature.

Reopen because the information was supplied, and I can reproduce a crash.

I start working on this. The thumbs embed in the pdf seems to have a strange
format. At least one filter have a type named "name". I not yet sure if the file
have been misgenerated or if the ThumbColormap object have a parse bug. At least
it doesn't crash anymore ...
I take it...

Remi, can you please check the patch I did for bug #139211? It fixed this bug as
well. It seems the old code handled only Indexed color spaces, but not
DeviceGray or DeviceRGB.

*** This bug has been marked as a duplicate of 139211 ***

The bug was in colormap filter parsing (using only array objects instead of also
accepting name objects when only one filter).
Using Gfx colormap is ok (you removed the bug) but you also removed the
optimisation I added for thumb colormap (most of the thumbs are created with a
common colormap). Creating one colormap at each reference is really a big job ...
(I never saw a thumb created with a none indexed CM. This is why I created my
own simpler class).
By removing it I'am afraid that the thumbs processing become still longer (and
it is already a pain ;-)
