I guess so! But I should have been clearer about the way I install packages. 
Instead of going through the workflow on the HelpOnPackageInstaller page 
(upload file, click on "install"), I tend to use the command line tool, which 
is also mentioned on that page.

So, given a pages.zip file, I run the following command:

python MoinMoin/packages.py i pages.zip URL_PATH

Here, URL_PATH corresponds to the published location of the wiki on the host.

For me, this almost always works, where failure is usually something to do 
with the permissions. In fact, I'm using a tool that I wrote to administer 
Moin instances, but the actual command issued is ultimately the same.

You might need to set PYTHONPATH to include the location of the MoinMoin 
package and also the location of the wikiconfig.py file. Otherwise, the 
program won't find what it needs and will just fail straight away.

As for the logging, you might want to look first at the general error log for 
your Web server. I'd have to remind myself about Moin's logging configuration 
if I were to provide any insight on this, anyway. ;-)
