Subject: rrd_graph: initialize new data member (fix #441)
X-Git-Tag: v1.5.0-rc1~135
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=154290c0015b6ee8e8867d89666ab2d0a008d9ff;p=thirdparty%2Frrdtool-1.x.git

rrd_graph: initialize new data member (fix #441)

primary_axis_format was added to image_desc_t but rrd_graph_init was not
updated to initialize it, resulting in this error when the garbage
values were used as axis labels:

(process:24893): Pango-WARNING **: Invalid UTF-8 string passed to pango_layout_set_text()
