The reason appears to be that raptor calls libxml2's xmlSetStructuredErrorFunc to set its raptor_libxml_xmlStructuredErrorFunc (redland/*/misc/build/raptor-1.4.18/src/raptor_{grddl,sax2}.c), but does not necessarily call xmlSetStructruredErrorFunc again to reset it to null.  Indeed, running soffice.bin under gdb, opening some .odt file and then closing soffice.bin, breaking gdb on xmlSetStructedErrorFunc hits in two places during file open to set raptor_libxml_xmlStructuredErrorFunc (see below), but never afterwards to reset it again (i.e., no call to raptor_finish -> raptor_sax2_finish -> xmlSetStructuredErrorHandler(NULL, NULL)).

Comment 1 Michael Stahl (allotropia) 2012-11-13 11:13:30 UTC 
i think reverting from d68113f3229d0ec8c84f77dcac3b64a3fd7e03e4
the change in unoxml/source/rdf/librdf_repository.cxx
should fix this.
it should not be necessary because since 16e72215c96ee734e2cf6d15a465577d289a1549 calling xmlCleanupParser
from atexit() works again.
Comment 2 Not Assigned 2012-11-14 14:01:25 UTC 
Stephan Bergmann committed a patch related to this issue.
It has been pushed to "master":

http://cgit.freedesktop.org/libreoffice/core/commit/?id=62af61b8f076c00eb045dca1c46275882e17ce6b

fdo#57055: Re-enable call to librdf_free_world



The patch should be included in the daily builds available at
http://dev-builds.libreoffice.org/daily/ in the next 24-48 hours. More
information about daily builds can be found at:
http://wiki.documentfoundation.org/Testing_Daily_Builds
Affected users are encouraged to test the fix and report feedback.
Comment 3 Stephan Bergmann 2012-11-14 14:07:45 UTC 
So I reverted now as per comment 1, and my little experiment from comment 0 now indeed shows a call to null xmlSetStruturedErrorFunc during exit (see below).

However, what librdf et al do there still looks wrong:  For one, according to <http://www.xmlsoft.org/html/libxml-xmlerror.html#xmlSetStructuredErrorFunc>: "For multi-threaded applications, this must be set separately for each thread."  So it is by pure luck that in my scenario the first two calls to set xmlSetStructuredErrorFunc are from the same thread as the final call to null it.  For another, I would assume that the raptor library would reset this global resource as soon as it is done and not only at exit.

Comment 5 Michael Stahl (allotropia) 2012-11-14 14:26:00 UTC 
there has been significant upstream work on raptor and we still have a version from 2009 or so, maybe that has improved (i definitely reported the xmlCleanupParser call upstream), we really should update it if i find the time...
Comment 6 Michael Stahl (allotropia) 2012-11-14 14:27:22 UTC 
i hate bugzilla. or firefox's caching of it. bah.
