When running ikiwiki rebuild I got error:
failed to syslog: Wide character in syswrite at /usr/lib/perl/5.18/Sys/Syslog.pm line 546
Ubuntu 14.04. ikiwiki 20150107.
What was on the next line after that message?
I suspect this is a bug which still exists in 3.20150614. I think I've now fixed it
for the next version of ikiwiki.
