If you enable Apport so it launches automatically to collect and submit crash data, install debug symbols for possibly relevant packages, and then make the crash happen again, then you can submit a new bug report that contains valuable information missing in this bug report. This should either determine what previously reported bug this is a duplicate of (and then you can provide any missing information there, and possibly get information about known workarounds) or, if this turns out to be a new bug not previously reported, provide the necessary information for the Ubuntu developers to investigate and fix the bug. After submitting the new bug report, you can mark this older bug a duplicate of the newer bug (which is *not* the same thing as marking the new bug a duplicate of this one, which you should not do).

First, read this carefully, if you haven't already:
https://help.ubuntu.com/community/ReportingBugs

Then, to enable Apport:
https://wiki.ubuntu.com/Apport#How%20to%20enable%20apport

Some of the debug symbols for yelp and the libraries it uses are available through -dbg packages, but for others, you'll need -dbgsym packages. -dbg packages are available for installation via the same software sources as the programs/libraries whose debug symbols they provide, but -dbgsym packages are provided in separate software sources. In this case, you'll need some of each type of debug symbol package. So, to enable -dbgsym packages, follow steps 1-4 at https://wiki.ubuntu.com/DebuggingProgramCrash.

Then install the debug symbols for yelp and the libraries it uses by running this command in the Terminal (or, if you prefer, by selecting each of these packages manually in Synaptic or the Software Center...but the Terminal way, in this case, is much easier, because you can just copy and paste the command into the Terminal). This is also a good time to make sure all the software in your Ubuntu system is up to date (there have been some updates to Maverick since you reported this bug, and some of those updates have been quite recent--it's important to see if perhaps this has been fixed already, even though it probably has not):

sudo apt-get upgrade; sudo apt-get install yelp-dbgsym gconf2-dbgsym libatk1.0-dbg libc6-dbg libdbus-glib-1-2-dbg libgcc1-dbg libgconf2-4-dbgsym libglib2.0-0-dbg libgtk2.0-0-dbg libice6-dbg liblaunchpad-integration1-dbgsym libpango1.0-0-dbg librarian0-dbgsym libsm6-dbg libstartup-notification0-dbgsym libstdc++6-4.4-dbg libx11-6-dbg libxml2-dbg libxslt1.1-dbgsym man-db-dbgsym xulrunner-1.9.2-dbg

To run that command, select the whole thing at https://bugs.launchpad.net/ubuntu/+source/yelp/+bug/716968 (it will probably have line breaks inserted in your email, which will prevent it from running properly), copy it to the clipboard, paste it into the Terminal, and press enter to run it.

In this case, the most important debug symbol packages to install appear to be yelp-dbgsym, libc6-dbg, libglib2.0-0-dbg, and librarian0-dbgsym. But there's no reason not to install the rest, and they may help significantly in producing a good bug report.

If you have any trouble performing any of the above steps, please post a comment here describing...

If you have any trouble performing any of the above steps, please post a comment here describing the problem.

Then produce the bug, but this time, run yelp in a different way--open a Terminal window and run the command:

yelp ghelp:about-ubuntu

That command performs the same action that happens when you do System > About Ubuntu. This way, you get to see (and include in your bug report) all messages written by yelp to standard output or standard error. Then create a new Terminal window (or, if you prefer, a new tab in the same Terminal window) and run:

yelp

That command performs the same action that happens when you do System > Help and Support.

In your new bug report, please make sure to include all the information included here (and also you may want to link to it, saying something like "I originally reported this as bug 716968 ..."), and also all the text from the Terminal when you ran each of those commands (but *not* the text from when you ran the commands that enabled apport, updated your system, and installed the debug symbols). Please note that, when you run the second command, it may cause more text to be written by the *first* command, in the first window/tab. So before running the second command, you should check in the window/tab associated with the first command, to see what text has been written so far, and then report what text (if any) was newly written by the first command when the second command was run.

After submitting the new bug report, you can use the green "Mark as duplicate" link near the upper-right corner of *this* bug page to mark this bug a duplicate of the new bug. Since the new bug will be reported as a crash by Apport (rather than as a non-crash bug, as was the case here), it will start out with private visibility. This is because the data submitted by Apport in a crash occasionally contains confidential or sensitive information, such as passwords or credit card numbers. In this case, since it's the help browser, the risk of that is low, so you might want to manually mark it public, or, as a compromise, subscribe me to the bug (so that I can look at it and see if I can determine if it's a duplicate of an already-reported bug). But you can also just wait for the "Apport retracing service" bot to remove potentially sensitive information and mark it public (or failing that, for Ubuntu bug triagers to do so)--it is not necessary for you to manually change the new bug's visibility, nor for you to subscribe me to it. If you do mark it public, or even subscribe me to it, you should make sure to read https://wiki.ubuntu.com/Bugs/HowToTriage carefully first, so you understand, and are able to assess, the possible risks.

Thank you for taking the time to report this bug and helping to make Ubuntu better. However, your crash report is either missing or challenging to deal with as a ".crash" file. Please follow these instructions to have apport report a new bug about your crash that can be dealt with by the automatic retracer.

If you are running the Ubuntu Stable Release you might need to enable apport in /etc/default/apport and restart.

Now open your file manager, navigate to your /var/crash directory and open the crash report you wish to submit.
If this fails you will have to open a terminal and file your report with 'ubuntu-bug /var/crash/_my_crash_report.crash' where _my_crash_report.crash is the crash you would like to report. If you get an error that you aren't allowed to access this report you will have to file it with 'sudo ubuntu-bug /var/crash/_my_crash_report.crash'.

I'm closing this bug report since the process outlined above will automatically open a new bug report which can then dealt with more efficiently. Thanks in advance for your cooperation and understanding.
