In my case (see bug 859723) this happens with Opera and KeepassX whenever I close the application with some of its content in the clipboard. Eg. I copy a password in KeepassX or something on a web page in Opera, then close the application.
I'm attaching the backtrace from bug 859723 for what it's worth.
