Important K 2.0.0 RC1 Installation Errors

Yeah, I've been having difficulty uninstalling components/modules/plugins from joomla 2.5x. Let me just say the uninstaller on joomla 2.5x is not impressive at all I will try the above, but not probably until this weekend as I have a very busy work week this week. Hopefully we can find the problem. Should I do a copy of the kunena database tables and then just do a new install of joomla 2.5.4 and go through the above steps and sql the kunena tables in after a kunena 1.7.2 fresh install?

I'd first try if my advice fixes the issue. Because of there's really no change between K1.7 and K2.0 installer at that point.

Alright, I was able to uninstall 1.7.2 and do a install of 2.0rc1. The Install went ahead and did not stop with errors. However, this is when i lay down the bad news. I now get this error when trying to access the component:

Fatal Error was detected!

Fatal Error: Call to a member function xpath() on a non-object in components/com_kunena/libraries/template/template.php on line 89

The error was detected in the Kunena Component.

I searched and found this post: www.kunena.org/forum/K20-Test-Reports/12...n-error-has-occurred

However, I went and deleted all kunena menu alias and then re-installed..still same problem. I notice the bug may have been addressed in the repository. Will there be a fix shortly?
