Comment 21 for bug 944624

Thanks, the logs don't have a lot of infos over the stacktrace though :-(

Could you try to reinstall the debs from the previous version:
https://launchpad.net/ubuntu/+source/nautilus/1:3.3.90-0ubuntu3/+build/3252050
or
https://launchpad.net/ubuntu/+source/nautilus/1:3.3.90-0ubuntu2/+build/3231502 (the previous one)

(should be basically downloading the lib and nautilus debs and dpkg -i those)

then restart nautilus (nautilus --quit; nautilus) and see if that's still an issue?

The duplicates here are all on amd64, I wonder if thats 64bits specific

The valgrind log also has quite some dbusmenu errors (set image) but that lib didn't change recently...
