I can reproduce this very easily. The behaviour is "mostly" correct.

 The empty src="" attribute causes the browser to locate
the image under the same url as the page, and this tries
to load the page a second time, this time as image ... not 
a zope bug IMO.

I'm guessing that the user is OP is doing something else in the
template which triggers a ConflictError, and therefore a
retry.

I can't reproduce it either.

The following line in a ZPT will cause Zope to render the Template twice:

<img src="">

You can test it with this line,using the external method printIt:

<img tal:define="foo python:here.printIt('FOO')" src="">

External Method:

import zLOG
def printIt(text):
    '''Print LOG-Informations from inside Zope'''
    zLOG.LOG("==>", zLOG.INFO, text)

When the ZPT is returned from a Python script, this Script is called twice, too.
