I can reproduce this bug on Ubuntu 12.04 64-bit with yelp 3.4.1-0ubuntu1.The test machine has a quad-core 3.2 GHz AMD Phenom II and when the bug occurs one of the cores constantly runs at 100% until closing yelp (tested for 10+ minutes).
It seems that high CPU usage is triggered by using the search bar in yelp. If a search query produces no results, load is normal. But if a query produces some results, high CPU load occurs. I'd say it this bug is quite similar to bug 268845 which was reported in 2008. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to yelp in Ubuntu. https://bugs.launchpad.net/bugs/872114 Title: Yelp causes 100% CPU usage Status in The Yelp Help Browser for Gnome: Confirmed Status in “yelp” package in Ubuntu: Triaged Bug description: Steps to reproduce: 1.
