[rrd-users] Segmentation Fault

[wiz]

Hello, all!
When i'm trying to graph (or just fetch) data from my rrd i'm getting a core.

RRD is a simple gauge generated from apache's logs.

$ rrdtool 'graph' '/tmp/graph.gif' '--start' '1154188604'
'DEF:down_link=hits.rrd:down_link:AVERAGE' 'AREA:down_link#b56447'

$ rrdtool fetch hits.rrd AVERAGE
Segmentation fault (core dumped)



$ rrdtool
