Simply importing template from webapp throws huge trail of exceptions

[relistan]

I've got AppEngine 1.1.2 installed and if I simply add this line in my
main.py:

from google.appengine.ext.webapp import template

which is straight out of this examples (and looking through the file
system appears to be a valid module), throws a huge trail of
exceptions.

Like:

<type 'exceptions.ImportError'>

Followed by:

ERROR 2008-08-26 20:01:30,619 dev_appserver.py] Exception

Am I doing something really ignorant here, or is something broken in
this appengine distribution?

Cheers

Ok, something IS wrong with this distribution. Simply substituting
1.1.0 which I still had lying around made the error go away. 1.1.1
seems to cause the same issue as 1.1.2 was causing. Can anyone
confirm this? Surely this would break nearly any Django-based
application?

On upload the code seems to run fine, it's only on the local
installation where it breaks.

Platform here is Ubuntu 8.04 running Python 2.5.2

Apologies all, I'm not sure what I did, but it appears that re-
installing 1.1.2 has resolved the issue. Perhaps I somehow corrupted
some config file since it was affecting 1.1.1 as well. In any case
it's resolved.

Cheers,
Karl
