Split off from bug 12056. Input such as x<nowiki>y</nowiki>z is converted to something like: x<del>UNIQ225ad7a62aaa0e75-nowiki-00000001-QINU<del>z where <del> is the delete character, 0x7f. Typcially this occurs in the pre-save transform, so the result is saved into articles, leading to diffs such as these: http://commons.wikimedia.org/w/index.php?title=Template_talk:AdminWelcome/en&diff=8765512&oldid=8763902 http://translatewiki.net/w/?title=Process/tasks&diff=prev&oldid=164002 All XML-style tag extensions are affected. On some installations this happens all the time, on others it happens randomly and is not reproducible. It has been reported on: * Roan Kattouw's Windows test server. Reproducible with PHP 5.2.4 cgi/fcgi, not observed in the same installation under the CLI SAPI. * Unknown servers in Wikimedia's app cluster. Is it server dependent or random? * Reproducibly on Bertrand Grondin's server at grondin.tuxfamily.org * Randomly on translatewiki.net, reported by Nikerabbit During an attempt to narrow down the problem on Roan Kattouw's server, an odd bug was observed where a Title object would disappear, triggering a fatal "cannot call member function of non-object". This may or may not be related.

Possible fix in r28004, please test.

Nikerabbit reports that it's fixed on BetaWiki.
We'll call this provisionally fixed. But it might be nice to remove the failure mode at some stage.
