Hello,
I wanted to create a gettext portable object template (.pot) file from
Norman Walsh's "DocBook: The Definitive Guide". Therefor I used:
xml2po -e -o book.pot book.xml
in http://docbook.svn.sourceforge.net/viewvc/docbook/trunk/defguide/en/
and received a segmentation fault. So I started gdb and got the attached
backtrace. Can any of you say, where the segmentation fault is produced
- in xml2po or libxml2/python-libxml2 - so I can file a bug-report?
xmllint validates the XML source if you fix the <tag> element in
refpages/elements/equation/refentry.xml (should be an sgmltag element).
CCing Danilo Segan, the maintainer of xml2po
Thanks for any help,
Regards, Daniel
The program being debugged has been started already.
Start it from the beginning? (y or n) Starting program: /usr/bin/python
/usr/bin/xml2po -e -o book.pot book.xml
