I can't think of a good way to fix the problem from this aspect besides
waiting for old cached page to expire, unless some sysadmin is happy to
nuke all existing Squid cached pages.
However if you have a list of affected pages as you're crawling HTML, which
we don't have, you can simply purge them in batch and recrawl those pages.
Could you share the bug's link?
There was no bug created in bugzilla... I submitted a patch[1] directly to
fix the bug once it was spotted.

Thanks
I checked with Jiang Bian and found out that this is still happening --
can anyone help Google out here? :-)

There was a bug in some Wikibase version deployed in July which caused
this
error, but a fix was backported soon and since
then I've never seen any
similar error as a logged in user. If you still see some errors only when
unlogged in at particular URLs (like what you described) now, it's likely
that those URLs got cached in Squid when the bug was live... In this case
purging those pages[1] should be able to fix the issue.
