Is it similarly as convoluted and difficult to have an explanation with, 
say, RuntimeExceptions?  For instance, with a document with only one 
sheet, one should not be able to remove the last sheet, right?

 >>> doc.Sheets.removeByName('Sheet1')
---------------------------------------------------------------------------
com.sun.star.uno.RuntimeException         Traceback (most recent call last)

/home/kevin/ram/temoa/branches/tmpp/<ipython console> in <module>()

com.sun.star.uno.RuntimeException:

 >>>

Which is correct of course, but not terribly elucidating (note the empty 
trailing colon).  Would this be a simple case of putting an RTL...string 
in removeByName in docuno.cxx?
