starting KMC console fails on CE 6.0.1

After installation on RHEL 6.3 from github sources (branch: falcon-working, cloned Jan 3rd 2013) after navigating to:
/index.php/kmc/kmc2

I get "500 Internal Server Error". It is caused by failed SQL query:

Suspicious part of SQL query is: ORDER BY (ui_conf.PARTNER_ID=). Installation went without problems.

I do realize that using latest sources to build the deployment may be prone to such errors, but this leads to the following questions:
1) is there any supported stable branch / tag that could be used for evaluation? I could make do even with specific commit number, just any snapshot in development history that I could use to get the product running...
2) what is the meaning of the version number 6.0.1 used when packaging sources? Is there any "newer" version? Which should I use? I missed that info in installation tutorials.

I understand that CE is open source and community driven edition of Kaltura product and comes without tech support, but honestly - just having one stable tag in git repository that can be used out-of-the-box would make a huge difference for evaluators. So far this has been a little discouraging....

Appreciate any ideas / help.

Thanks
