I resolved my issue and decided to post the solution in case someone will need something similar. The thing is that Javier was right - mptt is not working. I also tried to switch to Google Cloud SQL. But at the end I found a simple solution that was all the time in front of me - django-threadedcomments app (http://code.google.com/p/django-threadedcomments/). The project page seems a bit abandoned, but I found this tutorial that helped a lot http://django-threadedcomments.googlecode.com/svn-history/r120/trunk/docs/tutorial.rst . It worked for me, maybe that is not the best solution, but at least saves some time from implementing your own tree.
