Erm, you can reenable these by going to settings->dockers and selecting 'brushes' or 'layers', or by rightclicking a docker title and selecting 'brushes' or 'layers' there. This is not a bug. Also, next time you make a report, we need system information such as the operating system and which version of Krita you're using. If we do not get this information, we will also close the bug.
It would also be best if next time YOU go to user support forum like krita-artists.org instead with questions like this, regarding issues with usage. This website is very developer-oriented, while the krita-artists.org forum is user-oriented and much more user-friendly too.
