RTC and SVN plugins dont work together?

Hello there,

I just figured:

* Installed an Eclipse helios M5 zip on my ubuntu 9.10 machine
* Got the rtc 2002 pi archive and installed that ... worked fine
* Installed ANOTHER eclipse helios m5 ... and installed CDT and subversive plugins ... and now

a) in my "rtc" eclipse ... the jazz administration doesn work any more
(it shows up as "<Jazz>" and all the views seem to be empty)

b) in my "other" eclipse ... my SVN connected projects simply dont
show the SVN version number any more.

Thats pretty annoying for me.

Anyone out there with the same problem? And maybe a solution?
