elinks crashes by pressing 'n' on startup

[sgerwk]

1. open a document
2. press 'n'

Same result by clearing the search pattern (e.g., '/', remove all and enter) and pressing 'n'.

This should result in a "no previous search" or something like that. I believe it used to be, but no longer is.

Maybe I'll dig more into this in the next weeks.

@sgwerk, thanks for the report. Now message can be misleading.
