Defining a virtual node breaks munin-update

[ssm]

The following configuration fragment:

 [virtual.example.com]
  update no
  contacts no
  foo.update no
  foo.graph_title something

makes munin-update stop with:

[...]

2015-12-31 00:08:25 [debug][006619]: Writing sql to /var/lib/munin/datafile.sqlite.6619
DBD::SQLite::st execute failed: called with 3 bind variables when 6 are needed at /usr/share/perl5/Munin/Master/Update.pm line 282.
Can't use string ("foo.update") as an ARRAY ref while "strict refs" in use at /usr/share/perl5/Munin/Master/Update.pm line 303.

As soon as I add the "foo.graph_title", munin-update stops, leaving a sqlite datafile with defined tables, some node definitions, but no values:

# echo .dump | sqlite3 /var/lib/munin/datafile.sqlite.6619 | sed -e 's/^/     /g'

+1 that one is hitting hard, as most of my useful munin stats are based on virtual nodes :)
