Seeing the same thing. Attached a debugger, without debug symbols this is the best I can give you:

() Though I'm not particularly adept at gdb. Its hard to reproduce, takes sometimes up to 5 minuts of clicking around and entering text into the search box to get it to do it. ** Attachment added: "yelp chewing CPU" http://launchpadlibrarian.net/12526533/screenshot1.png -- High CPU usage by yelp https://bugs.launchpad.net/bugs/199860 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
