enabling com_zimbra_html freezes login screen

[adex]

I have enabled the portal page on my cos (zimbraFeaturePortalEnabled TRUE
zimbraPortalName example)

when i enable the "com_zimbra_html" zimlet ,the login screen freezes.
If i disable the zimlet users can log in.

also downloaded and deployed the com_zimbra_html from the zimbra svn at sourceforge

Im using zcs open source edition 5.0.9_GA on Centos 5

I can confirm this. I get a javascript error (str is undefined) in line 365 of /zimbra/js/ajax/boot/AjxPackage.js:

replaceObj()(/(^|[^\\])\$\{app\.([\$a-zA-Z0-9_]+)\}/g, undefined, Object contextPath=/zimbra currentSkin=beach)AjxPacka...cjw%3D%3D (line 365)

It appears that the refresh property in the manifest cannot be left out, but must have a value. Use a very high value if you don't want a refresh.
