Drafts for postings get corrupted in user control panel

When saving a draft from the normal post editor and then opening it in the user control panel it gets corrupted with weird tags.

Steps to reproduce:

1) Login as administrator/administrator at http://www.try-phpbb.com/32x

2) go to the only forum, click "new topic" and write a post containing at least two words (do not submit), my sample posting:

Save my draft.

:mrgreen:

3) click "safe draft" and confirm

4) go to user control panel, click "manage drafts"

5) open the draft and see this in the editor:

<r>Save my draft.<br/>

 <E>:mrgreen:</E></r>

The editor should not contain these tags.

I noticed: If you edit and save the draft within the user control panel the tags are gone.

Upon further investigation the problem seems to be, that the drafts are saved this way:

$message_parser->message

in posting.php line 722

but ucp_main.php does not use the message_parser to load or save the drafts.
