this sounds like a version mismatch problem. In general, you should try
to make sure to use a version of RKWard that was compiled specifically
for the version of R in use.

This is a bit of guesswork, but it sounds like the R version on the
former system is a development/SVN snapshot. In this case, your only
safe bet will be to compile RKWard from source, too. Fortunately, this
is relatively easy on Ubuntu:

sudo apt-get build-dep rkward
xzf rkward-0.6.3.tar.gz    # get it from http://rkward.kde.org/download
cd rkward-0.6.3
mkdir build; cd build
cmake .. -DCMAKE_INSTALL_PREFIX=/usr -DR_EXECUTABLE=/your/path/to/R
make
sudo make install

BTW, my very first guess would be that this version of R was compiled
without the --enable-R-shlib configure option. In this case, you will
have to recompile it with the option enabled.

A different, and very comfortable way to use RKWard with a fresh version
of R is installing R from Michael Rutter's archive:
https://launchpad.net/~marutter/+archive/ubuntu/rrutter
and a matching version of RKWard from one of our "CRAN version of R"
PPAs:
https://launchpad.net/~rkward-devel

Probably this is what you have on the 32bit box(?).

If I guessed all wrong, a sessionInfo() of the R version on the
crashing machine might be helpful.

Thanks for the praise. Hope this helps some. For follow-up questions,
please post to rkward-devel at kde.org (we have moved).
