Ok, the setup is more contrived as I now figured out (but it still
happens in HEAD):

- The mouse needs to hover over the link in such a way that it will
  be on a link again after pressing SPC (this is easy to trigger on From:
  and articles that fit on a screen)
- elscreen needs to be loaded and started
- elscreen needs at least two tabs(!), with a single tab it doesn't trigger

I'm unable to make any good backtrace of this happening, other
than simply

command-error-default-function

I hope this helps reproducing.  If you have other ideas how I can
debug it myself, please tell me.
