From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.8) Gecko/20050524 Fedora/1.0.4-4 Firefox/1.0.4 Description of problem: The pyuno bibliography program bibus works properly under openoffice.org-1.9.104-2. I upgraded to the newer openoffice.org-1.9.112-1.1.0.fc4 and reinstalled bibus. When I attempt to insert a citation from Bibus (a python program), I get a seg fault. That's very odd for a python program - the python interpreter should catch it. Alternatively, I think that the culprit could be a bug in the newer openoffice.org-pyuno in the new openoffice.org. I don't know how to debug it any further. Note that downgrading to openoffice.org-1.9.104-2 (from the original fc4 distribution has fixed the problem). Bibus v1.0.0 is available at http://bibus-biblio.sourceforge.net/ If there's a way that I can debug the problem, let me know. Version-Release number of selected component (if applicable): openoffice.org-1.9.112-1.1.0.fc4, openoffice.org-pyuno-1.9.112-1.1.0.fc4 How reproducible: Always Steps to Reproduce: 1.install bibus (as root), doesn't matter if you choose socket communication or pipe communication, but set it up for all users 2.run oowriter (as normal user) 3.run bibus (as normal user) 4.Click on a citation in bibus (create one if there isn't one already there) 5.From menu Openoffice.org, select insert citation Actual Results: Segmentation fault (from bibus). oowriter keeps running (but does nothing) Expected Results: citation mark and reference get inserted into the oowriter document Additional info: Normally, you'd think that this was a bibus bug, but since the program works fine on the previous version of openoffice.org, I tend to think that it's Openoffice.org, or pyuno that's causing the problem. If pyuno is screwed up, then a lot more Openoffice.org addons will probably fail.
as a workaround does running as root... echo 0 > /proc/sys/kernel/exec-shield fix this ?
Cool, turning exec-shield off fixes the problem. Is there a way that I can turn off exec-shield in a more fine-grained way, or does something just need to be recompiled? Let me know if there's anything else you'd like me to test.
I cocked something up, and I know what I did, but I'm not sure why it had the effect it did, see http://qa.openoffice.org/issues/show_bug.cgi?id=51385
fixed in 1.9.113 in rawhide, I'll also push a fc4 update
