Summary: rkward crashes when working with xml files (R4X)

Initial Comment:
Hi:

I guess I have some problem with my own R script for processing xml files (through the usage of R4X package). But the fact is that RKward crashes every time I attempt to run this script (reporter.00.5.r, attached), due to this part: \"xmlTreeParse(xml_r)\"

I get a prop screen with this error:
-----------------------
*** caught segfault ***
address 0x3e, cause \'memory not mapped\'
-----------------------

However, when I run the same script reporter.00.5.r from the command line, with:
 
 Rscript reporter_00.5.r

the script seems to read the line with the \"hello\" output in the console, at least.

Oh well, in case this can help the authors of rkward to improve the error detection and warnings for the user, instead of crashing the program. 

More details: RKward: 0.5.2. KDE: 4.4.2, OS: GNU/Linux (Ubuntu Lucid 10.04), R: 2.10.1

Fir this script to run, some extra R packages need to be installed: XML, R4X and their dependencies. The commands to install them are included (commented) in the reporter.00.5.r script, as weel as the linux dependencies for the xml package to install.
