Bug with single quote in feature fields

When modifying a feature element (text field) with a single quote in it, the following error is logged:

The feature definition in PostGIS is:

Table "public.features"
Column | Type | Modifiers
----------------------------------------------------------------------------------------------------------------
oid | integer | not null default nextval('features_oid_seq'::regclass)
name | character varying |
geoLocation | geometry |
text | character varying |
Indexes:
"features_pkey" PRIMARY KEY, btree (oid)
Check constraints:
"enforce_dims_geoLocation" CHECK (ndims("geoLocation") = 2)
"enforce_geotype_geoLocation" CHECK (geometrytype("geoLocation") = 'POINT'::text OR "geoLocation" IS NULL)
"enforce_srid_geoLocation" CHECK (srid("geoLocation") = 4326)
