https://zh.wikipedia.org/?diff=27825404&oldid=26993245 A use tried to edit a template, but when he/she save his/her edit, it also break the image below which he/she haven't edit and it change the image into undefined.
I was able to reproduce this bug altering the template under the text '维基数据'. The media link changes without the user being involved. https://zh.wikipedia.org/w/index.php?title=User:John_Vandenberg/MainPage&action=history
A simple test case '. [[File:Wikimedia-logo.svg|45px|center|link=]]' change '.' to '..' and save. or https://en.wikipedia.org/w/index.php?title=User:John_Vandenberg/test&oldid=565743208&veaction=edit Results: 1. Image disappears 2. Saving changes the result to: '.. [[undefined|center|link=|nullxnullpx]] '
On it.wp as well: http://it.wikipedia.org/w/index.php?title=Cappella_Sansevero&diff=prev&oldid=60497840
The following round-trips fine at http://parsoid.wmflabs.org/_rtform/: [[File:Wiki.png|45px|center|link=]] This makes it likely that this is actually a VE issue. Moving to the VE component for investigation.

Change 79256 merged by jenkins-bot: Fix traversal for images with link='' https://gerrit.wikimedia.org/r/79256
This is now fixed in master (but images with link= will trigger a VE corruption warning - to be fixed tomorrow). It should be pushed to production in the next few days.
