bug#29611: 25.3; help navigation error

[Alex Branham]

Clicking on a specific link from a specific help buffer results in an error. On 
Emacs 25.3, from emacs -q:

M-/ (dabbrev-expand)

C-h v dabbrev-select-buffers-function

<TAB> <TAB> <RET> (navigate to the second link and click it)

results in:

apply: Wrong number of arguments: #[(fun file &optional type) "ÄÅ!ˆÆ=ƒ.ÇÈ     
!Á\".É  
#.Ê@!ˆËÌ!ˆAƒ+.Ab‚..ÍÎ!)‡" [file fun type location require find-func 
C-source help-C-file-name indirect-function find-function-search-for-symbol 
...] 4], 1

Thanks,
Alex
