bug: objectify removes text on replace()?

Hi,

with lxml 2.0.4 I get text removed when I replace a node. The text 
after the replaced node vanishes....

-----------------------
import lxml.objectify
import lxml.etree

xml = lxml.objectify.fromstring(
    '<foo><bar>before baz<baz/>after baz</bar><bar/></foo>')
print lxml.etree.tostring(xml, pretty_print=True)
print 50*'-'

baz = xml['bar']['baz']
xml['bar'].replace(baz, lxml.objectify.E.holler())

print lxml.etree.tostring(xml, pretty_print=True)
-----------------

Prints out:

<foo>
  <bar>before baz<baz/>after baz</bar>
  <bar/>
</foo>

--------------------------------------------------
<foo>
  <bar>before baz<holler
