The work-around was just to uninstall gap-autpgrp (and the other packages with old manuals) when running sage and its tests.

Thankfully, I can confirm this patch works, even when gap-autpgrp is present.

$ sage -c 'print(gap.help("SymmetricGroup", pager=False)[:100])'
  
  50 Group Libraries
  
  When you start GAP, it already knows several groups. Currently GAP init

$ sudo aptitude install gap-autpgrp 
[..]
$ sage -c 'print(gap.help("SymmetricGroup", pager=False)[:100])'
Traceback (most recent call last):
  File "/usr/share/sage/bin/sage-eval", line 10, in <module>
    eval(compile(s,'<cmdline>','exec'))
  File "<cmdline>", line 1, in <module>

    raise RuntimeError(message)
RuntimeError: Gap produced error output
Error, no method found! For debugging hints type ?Recovery from NoMethodFound
Error, no 1st choice method found for `+' on 2 arguments

   executing ? SymmetricGroup
# exit code 1

$ sudo aptitude install -t sid-sage gap gap-core gap-libs gap-online-help
$ sage -c 'print(gap.help("SymmetricGroup", pager=False)[:100])'
  
  50 Group Libraries

I also got similar results when running the gap.py doctests.
