Unable to use gdb to capture any info: gdb becomes completely unresponsive once I have started the yelp process(es) (ie cannot issue commands like "backtrace full", or anything else). However, before gdb goes away permanently, I see this:

Also, the CPU usage remains way too high (about 65% in Xorg, compared to less than 1% before the yelp run) and the memory usage stays too high as well (about 2.5 GB, compared to about 0.8 GB before the yelp run). Once I have killed the gdb and yelp processes via the putty link, the following line appears immediately below the last quoted line above: " Terminated spen...@bigneo:~$ " Note that the theft of the CPU cycles and memory appears to be associated with running yelp with a nontrivial parameter (ie "ghelp:about-ubuntu"). When I run yelp by itself (ie no parameters), I get the error message reported in Bug #425709: " ch...@chris-desktop:~$ yelp (yelp:10789): Yelp-WARNING **: Yelper initialization failed for 0x95d0e20 OMF category 'Applications|Other' not recognised, ignoring. A dialogue box appears after around 20 seconds: Unable to load page The requested URI "file:///fakefile#index" is invalid [OK] " One other thing to note: The whole reason I even clicked "About Ubuntu" in the first place was that I was trying to upgrade my installation of Firefox 3.0.17 to something a little more recent (3.5, 3.6, 3.7). However, none of the packages I downloaded from "PPA for Ubuntu Mozilla Daily Build Team", and tried to install actually installed. When I couldn't upgrade Firefox, I decided to enter a bug against Firefox 3.0.17 for Ubuntu (which often, but not always, failed to display properly the pages served up by my Linksys BEFSR41 router: the tab deck was usually missing). Part of the bug reporting process is to send info provided from "About Ubuntu". Maybe some part(s) of the Firefox 3.5 - 3.7 packages actually _did_ install, and corrupted yelp or the ghelp:about-ubuntu repository somehow? Please let me know if I can try anything else to try to fix this problem. -- Gnumeric help 100% loads processor https://bugs.launchpad.net/bugs/268845 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
