Let me first say that zathura is amazing and that I don't know how many times I entered "PDF viewer for Linux" into Google or DuckDuckGo before finding zathura :).

In my configuration, I was trying to map the key "j" in presentation mode to scroll forward one page. I already managed to do this via

map [presentation] j scroll full-down

On my way there, I tried the following line

map [presentation] j feedkeys "J"

which leads to a segmentation fault when "j" is pressed in presentation mode. I admit this key mapping is stupid, because "J" is only used in fullscreen mode, but still, I thought that a segmentation fault should be reported.

Thanks!
