This is on trunk Revision: 37484 and still in current trunk (Révision : 37823)
I have a rather long wiki page.
When I use section edition (any section), saving gives a blank screen.
Then I go back to the page and the whole page is replaced by one single line like:
the text "PK" followed by hex "0003 0004 0014 0008"
Then it is necessary to rollback the page from the version before the section edit.
Additional info:
It does not happen on short pages. I have not been able to find time to reduce the offending page to a demo case 😑
The error logs say there is a PHP memory exhaustion but when i upgrade my memory from 128M to 256M, it exhausts just the same :
