Invalid e-tag when using mod_deflate

Binary package hint: apache2

When using mod_deflate apache sends invalid e-tags to the client. This breaks use of the if-none-match tag, because apache doesn't recognize its own e-tag and resends the file instead of sending a "304 Not modfied"

Tags look like this: Etag: "2106e9-2c-3e9564c23b60"-gzip instead of Etag: "2106e9-2c-3e9564c23b60-gzip"
pay close attention to the quotes..

This seems to be the result of a wrong bugfix. More details are here:
https://issues.apache.org/bugzilla/show_bug.cgi?id=39727
A bugfix for mod_deflate is checked in already here: http://svn.apache.org/viewvc?view=rev&revision=740149

It would be great if we could have this fix for hardy-bugfixes
