Thanks for the advice to corep about the libstdc++5 in the subject "rational application developer 7.5 on ubuntu 9.10 karmic koala 64bit"
When you try to run RAD after selecting Workspace to Workspace Launcher by pressing the OK button the message "An error has occurred. See the log file /home/madnick/test/.metadata/.log."

Please'll show how to solve this problem.
I have the same problem.
I also installed the libstdc++5_3.3.6-18_i386 on my Ubuntu 9.10 32-Bit. I installed RAD 7.5.3 and got the same error.
Today i installed the Version 7.5.4 and there was also the same error.
The "export GDK_NATIVE_WINDOWS=1" workaround did not work for me; however, I was able to get RAD started by copying over the .metadata folder from an existing Eclipse workspace.
It seems to be a problem with the Welcome screen, though (which makes sense since one of the linked articles mentions issues with xulrunner), so if you activate the Welcome screen it crashes again and then crashes on restart as well.

Thanks for this advice, to copy the .metadata folder works for me too.
The Export GDK_NATIVE_WINDOWS=1 also didn't work in my case.
I got the same issue with RSA 7.5.4 on Karmic 32bit.
I've found the workaround at http://employees.org/~abhinav/blog/2009/10/getting-eclipse-3-4-x-working-on-ubuntu-karmic-beta/ :
'To get this working, just add the following to eclipse.ini on a separate line:
I was facing same errors and things worked after I installed xulrunner 1.8 using Synaptic and then ran command update-alternatives --config xulrunner to set the active xulrunner to 1.8 instead of 1.9
