Redmine

Hello everybody!

I've a strange issue:

I've upgraded redmine from redmine1 to redmine2.0.4.
When I go to some project and add new file to issue of this project I see double insertion:

File info.pdf added
    File info.pdf added

Comment Edit

Some text...

Both are the simular in brouser (firebug output):
<li>
<strong>File</strong>
<a href="/attachments/download/19736/info.pdf">info.pdf</a>
added
</li>
<li>
<strong>File</strong>
<a href="/attachments/download/19736/info.pdf">info.pdf</a>
added
</li>

I don't see any anomalies in log file after inserting info.pdf:
