TYPO3 Core

I cannot reproduce this problem with the default configuration(s).

Have you installed an extension that extends t3lib_parsehtml_proc?

Please explain what html code you get in the RTE and in the frontend, and what html code you think should be produced.

Here is the source code in the backend,
"<hr />

"
The "" show you that the cusor is really positioned 2 line below so there is two blank line result of two press on the save button.

And here is the code in the frontend

<p><hr>
</p>
<p> </p>
<p> </p>

I would expect no <p>&nbsp</p> to be added. I don't know why saving create those tags.

I don't know how to know if an extension extends t3lib_parsehtml_proc. Can you tell me which one to look at or do you want to have my extension's list to see by yourself?
Thanks

Fixed in version 1.1.6 on TER and in TYPO3core CVS, branch TYPO3_4-0.

Note: version 1.1.6 requires TYPO3 3.8.0+.
