Not sure of the right forum for this as it is an upgrade rather than a new install - so please move if necessary.

Just ran an upgrade on our server. Everything went smoothly as usual (great job again guys) except for one of the non-standard zimlets - asterisk - did not update correctly.

Updating non-standard zimlets...
        com_zimbra_asterisk...failed. This may impact system functionality.
I also tried post-install to deploy this zimlet from the zimbra-experimental folder, and it also failed from there.

It creates the com_zimbra_asterisk folder, and copies just one file into the folder asterisk.css but all other files are missing.

This is not an immediate show-stopper for us as we are just beginning to experiment with the integration but, it might be important for others.
