Description:
After a successful page edit using action=edit, the server returns an HTTP 500 code (with an empty body) instead of a normal response. This was encountered on http://test.wikipedia.org repeatedly. (Note that edits that fail for various reasons return proper error/failure messages.)
This bug appears to have been introduced between r33962 and r35960, although I am unable to diagnose further.
