[R-pkg-devel] Strange CRAN WARN: useraccount - Alias wurde nicht gefunden.

Dear All,
I get a strange warning in German (!?) here: https://cloud.r-project.org/web/checks/check_results_packager.html
It hints to sections
- 'Generic functions and methods',
- 'System and foreign language interfaces' and
- 'Writing R documentation files'
in 'Writing R Extensions'.
The error occurs on windows only (so far).
I can't reproduce the error (I don't have a windows machine), but I am sure that
I don't have or refer to any object called `useraccount` in that package.

Has anybody have any idea, hint or suggestion?
Thanks anyway,
Dominik
