Hello all,
I have a Fedora 16 and also RHEL6 WS that are 64-bit installs. I can install and run the zdesktop just fine. The odd thing is that the zimlets fail to install properly. Some do but most of them don't. The one I really would like is the com_zimbra_url. I can install it, restart ZD, and it still does not show up in the list under prefs. If I install on a 32-bit Fedora 16, for example, all of the zimlets show up in the prefs panel (including the URL links one).

Any idea what could be the difference between 32 and 64-bit install? Missing some 32-bit compatibility libraries or something?

I get the following errors in the zdesktop.log:
