Umbraco 4.5 - Problems when save & publish package

I have updated my package to be compatible with umbraco 4.5

When I create the package I receive an error:

A potentially dangerous Request.Form value was detected from the client (ctl00$body$tb_actions="<Action runat="insta...").

After some tests I found the problem in the "Package Actions" section.
My package create a tree node and this is the code (already used for umbraco 4.0.x.x)

<Action runat="install" alias="addApplicationTree" silent="false" initialize="true" sortOrder="6" applicationAlias="developer" treeAlias="houseKeeping" treeTitle="Housekeeping" iconOpened="folder_o.gif" iconClosed="folder.gif" assemblyName="FALMHousekeeping" treeHandlerType="loadHouseKeeping" action="" />

If I remove this code the package is saved correctly

This is the stack trace of the error:

Valore potenzialmente pericoloso Request.Form rilevato dal client (ctl00$body$tb_actions="<Action runat="insta...").Source file: c:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files\root\45fd5400\8bd1a1e6\App_Web_editpackage.aspx.5d1c7564.u2wgxejz.0.cs     Row: 0

This sounds like a bug to me, you should report it on Codeplex.

For now, you could just turn request validation off in the web.config, but don't leave it like that if you're going to deploy the site that you're creating this package in!
```
<configuration>
   <system.web>
      <pages validateRequest="false" />
   </system.web>
</configuration>
```
