Ok, thanks. There was also another reply which for some reason unknown
to me didn't appear in this thread so I'll just quote it here:

Hi Kees,
I have also seen similar problems from time to time, often in cases
where it
is difficult to isolate the problem in a nice way. Typically such
problems
could be caused by an invisible StyleBox, a peculiar invisible
character, an
invisible embedded cell or errors in the parsing of the mathematical
structure. If you look at the internal BoxData structure of a
StandardForm
Input cell (use the menu command "Show expression"), it is easy to
understand that pasting of expressions into such a structure sometimes
might
cause some errors. You might try to convert the expression into
InputForm
(by Shift+Ctrl+I in Windows) and back again (by Shift+Ctrl+N). Then the
expression is first turned into a string or TextData object, and then
turned
back into a BoxData structure. This might help or might mess things up
worse, which is hard to predict. You could also try to convert it to
InputForm, copy it and paste it into some external editor, and check
what
happens. Maybe you might correct something and then you might paste
back
into a Mathematica Input cell.
There is also a chance that my buttons "StyleRemove" or
"CopyAsInputFormK"
might help. They use other mechanisms than those built into "Convert To
InputForm" and "Convert To StandardForm". The buttons are located on my
SetFaceAndFont palette, see

Thanks for the extensive response Ingolf, I'll have a go at your hints
tonight.
