Subject: python-extractor when extracting keywords from file.

Date: Wed, 27 Jun 2007 23:40:41 +0200

Package: python-extractor
Version: 1:0.5-2
Severity: grave
Justification: renders package unusable

Hi !

I have a very strange behaviour when I try to extract keywords from a file.
Here a pydb strace of the execution of the extract.py example file on a
textlive-pstricks doc distribution pdf file :
    $ pydb ./extract.py /usr/share/doc/texlive-pstricks/generic/pstricks/voss/bsp02.pdf

Another strange thing is that I tested the extract on another computer and I
experienced no crash.

So I hesitated between "normal" (because on another computer it does not crash) and "grave"  severity. I choosed the last one because on my computer, it crashes and render the package unusable ;-)

I hope we will able to find the origin of this problem.

Cheers,
Romain.

Hi !

It seems that it is related to libextractor itself, here a gdb and a

I've tried it on sid/i386 (as you) and didn't encounter that problem in
the first run:

(sid_i386)user@debian:/usr/share/doc/python-extractor/examples$
./extract.py /usr/share/doc/texlive-pstricks/generic/pstricks/voss/bsp02.pdf
Keywords from
/usr/share/doc/texlive-pstricks/generic/pstricks/voss/bsp02.pdf:
format - PDF 1.2
mimetype - application/pdf
(sid_i386)user@debian:/usr/share/doc/python-extractor/examples$

then, i installed libextractor-plugins, and could reproduce the problem.

Hi !

Christian Grothoff accused the libgsf to be the origin of the bug, and
he was right.

I downgraded libgsf version from 1.4.4 to 1.4.3, and this segfault
disapeared.

I reported a bug #431104

Thanks,
Romain.
