[Rd] 2.8.0 release bugs (PR#13210)

[janek musek]

Dear colleagues,
Thank you very much for information, the application of patches will
probably help. I apologize for answering delay due to my absence for some
days and for bothering you with my asking. I simply followed the suggestion
to report the possible troubles during the use of this R release (the only
one I must say) and certainly did not intend to cause any inconveniences.  
Best regards,
Prof. Dr. Janek Musek
