In recent versions of Ubuntu Linux (or other distributions that use its kernel) the Opera crash logger no longer works out of the box, following changes made by Canonical/Ubuntu.
Internally we are testing an updated version of our crash logging tool that is unaffected by these changes. We hope to provide this shortly in a forthcoming snapshot. In the meantime, Ubuntu users who wish to re-enable Opera crash logging can do so via the work arounds outlined by Alex Murray on askubuntu.com.
