Hello. With an SVN version of Mediawiki, Offline on my test wiki, calling index.php?title=%E7%89%B9%E6%AE%8A:%E5%8F%83%E6%95%B8%E8%A8%AD%E7%BD%AE (which is Special:Preferences), as a logged in user, causes child pid 10600 exit signal Segmentation fault (11) as seen in /var/log/apache2/error.log

This is not a helpful error message. You will need to run Apache under gdb to get anything sensible out of this.

gdb /usr/bin/apache2 run -X

View the page in your browser, it should hit the segfault and gdb will break out to another prompt. Then:

bt

That will give you a backtrace which will hopefully allow you to work out what component to file a bug against.

So, just like https://bugzilla.wikimedia.org/show_bug.cgi?id=9365 , this is probably not a Mediawiki problem, but a php5.3 problem.

It is overwhelmingly unlikely that bug 9365 has anything to do with this one. Segfaulted is the natural state of rest for a C program, developers must constantly strive keep their programs in the unsegfaulted state. You are seeing one of the many cases where they failed to do that perfectly.
