Thanks for the explanation!  Since the second option is 'clearly not
recommended' I have only one option ;-)

So, now I have set
    Sys.setlocale("LC_MESSAGES", "C")
and this seems to work for tracebug.

I'll see if that causes any bad side effects elsewhere.

Anyway, changing the messages to English is not a problem for me, so I
am happy with that option.

If that limitation stays, it should be stated in the manual.

But IMO such a line in the documentation sounds really strange:  Full
functionality of tracebug is available for English speaking users only.
So, it would be great if there was a more 'localization robust' solution.

Thanks again.  Off to some visual debugging...
