django 1.2 was requested, but 0.96.4.None is already in use

[Sagi]

I am encountering a sporadic issue with requests failing because
"django 1.2 was requested, but 0.96.4.None is already in use".
The first two lines in my main.py read:

from google.appengine.dist import use_library
use_library('django', '1.2')

...so I'm not sure how come 0.96 is already in use.

This has been affecting my production site for a while and I'm at a
loss on how to remedy it.

The site might be up and running fine for a couple of days and then it
out of nowhere (no new deployment) refuses to serve requests because
of this and in order to fix it all I do is upload a new version with a
trivial change (e.g. an extra empty line somewhere).

The full error is:

<class 'google.appengine.dist._library.UnacceptableVersionError'>:
django 1.2 was requested, but 0.96.4.None is already in use
Traceback (most recent call last):
File "/base/data/home/apps/s~dingitapp/1.356297547119531589/

Any suggestion?

Perhaps worthwhile mentioning:

1. templates are the only part of django I'm using
2. main.py is my only script handler
3. I'm using python 2.5
