It seems the Bulgarian dictionary from the various mirrors is not complete. If you look at what is downloaded, you will see that there is a bg_BG.dic, but no corresponding bg_BG.aff. Of course, this cannot work. If you know a working Open/LibreOffice (.oxt) extension with the Bulgarian dictionary, download it, rename it to .zip, extract the .dic and .aff from it, and copy the files to the folder mentioned in Options > Spell Checking.
My mistake, I was not looking at the right place. The aff file is there.
