libphp5.so segmentation fault - apache2+mediawiki

[purecharger]

Description: Ubuntu karmic (development branch)
Release: 9.10

apache2-2.2.12-1ubuntu2
php5-5.2.10.dfsg.1-2ubuntu3
mediawiki-1:1.15.0-1.1

When doing simple navigation around my MediaWiki main installation, the apache child processes are constantly segfaulting, showing up in the error.log.

Here is my debugger output:

Program received signal SIGSEGV, Segmentation fault.

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. I have classified this bug as a bug in php5.

Sorry for reporting a duplicate, but I can't even find the duplicate bug!!

Clicking this link:

Says I dont have permission to view it, and searching for the description of the duplicate yields no results.

Where is this phantom duplicate?

Thanks.

Is this a duplicate of #420389 instead?

I dont see a backtrace for the segfault in 420389, and that bug only mentions libgcc_s, libuuid and librt. My defect specifically comes out of libphp5.so.
