gnome-help excessive CPU usage

Thank you for taking the time to report this bug and helping to make Ubuntu better. This bug did not have a package associated with it, which is important for ensuring that it gets looked at by the proper developers. You can learn more about finding the right package at https://wiki.ubuntu.com/Bugs/FindRightPackage .
For future reference you might be interested to know that a lot of applications have bug reporting functionality built in to them. This can be accessed via the Report a Problem option in the Help menu for the application with which you are having an issue. You can learn more about this feature at https://wiki.ubuntu.com/ReportingBugs.

What are you talking about!?
The package is yelp, it's specified in the OP!

When reporting a bug you have to specify which package it affects in launchpad's system. To assign this bug to a package, click the drop-down menu next to "Affects: Ubuntu" and in the package entry field enter yelp. Then click save changes.

This is ridiculous!

The package was specified in the OP, you have bug triage helpers that can do that.
It's not enough that we have to go to the trouble of registering on this site to help you, when we're actually registered and come up with a post, this is how you deal with it.

Stellar performance there!</sarcasm>

Hello folks, To maintain a respectful atmosphere, please follow the code of conduct - http://www.ubuntu.com/community/conduct/ . Bug reports are handled by humans, the majority of whom are volunteers, so please bear this in mind.

Does the applications hangs or it's just use that amount of CPU while doing nothing? if it hang could you get a backtrace of that that'd help us to see where the issue is. thanks.

The OS remains responsive, including the help and logout window.

Thank you for posting this bug.

What are your hardware specs?

Does this happen in Lucid?

My hardware specs have changed ever since I submited this bug report.
I now have a quad8300 intel cpu wich does't take the initial 25 seconds of
100% cpu usage, but it still takes around 7 seconds of 100% cpu usage.
And yes, it happends in Lucid.

xor, thank you very much for testing this in Lucid and helping to make Ubuntu better. I have an AMD dual-core and opening yelp from the Terminal I went from 10%/5% to 50%/100% but the 50%/100% was sustained for less than a second. While for modern hardware this is no sweat, this is certainly an issue for less resource available hardware. Hence, it seems this should be marked as wishlist. As well, I am confirming this bug.

I am able to reproduce this on a Maverick amd64 system running a 2.2 GHz Intel Core 2 Duo processor (by running the command "yelp ghelp:user-guide" -- I cannot try running yelp with no arguments, since this system is affected by Bug 433504). The CPU spikes to 100% for at least 4 seconds.

I am also able to reproduce it on a Natty i386 system (also with the command "yelp ghelp:user-guide"). That system is a VMware Workstation virtual machine with the 2.2 GHz Intel Core 2 Duo machine (running Maverick amd64) as the host system. The Natty guest system runs yelp 2.30.2-0ubuntu1. The VMware Workstation version (in case it's relevant for benchmarking or other purposes) is 7.1.3 build-324285.

I neglected to mention it before, but the Maverick amd64 system runs yelp 2.30.1-0ubuntu1.

This issue is also present in Ubuntu 11.10. Just having the help open and sitting there consumes 100% CPU.
