Subject: rss: protect against nil field
X-Git-Url: https://git.netwichtig.de/gitweb/?a=commitdiff_plain;h=09f54bf35cdcdc278373521f6b4a3928ed81f744;p=user%2Fhenk%2Fcode%2Fruby%2Frbot.git

rss: protect against nil field

This happens when the filter tries to wrap a non-existing field, and in
custom filters it's probably a sign that the wrong field are being
accessed. It would probably be nicer to raise a warning about this, but
I'm too lazy to add that now.
