Hello,

I use backuppc 3.1.0-4 on a debian/lenny system to backup four remote
hosts. According to changelog and source, some graph with information
about the pool size should be displayed in the webinterface.
Unfortunately, this is not the case.

rrdtool (1.3.1-4) is installed and the rrd-file at
/var/lib/backuppc/log/pool.rrd seems to be updated regularly as well.

I even checked the command to create the graph image, which is used at
/usr/share/backuppc/lib/BackupPC/CGI/GeneralInfo.pm, and it seems to
work:

$ /usr/bin/rrdtool graph - --imgformat=PNG --start=end-7w --end=-300 
--title="BackupPC Pool Size (7 weeks)" --base=1000 --height=100 --width=600 
--alt-autoscale-max --lower-limit=0 --vertical-label="" --slope-mode --font 
TITLE:10: --font AXIS:8: --font LEGEND:8: --font UNIT:8: -c BACK#FFFFFF 
DEF:ao="/var/lib/backuppc/log/pool.rrd":ckb:AVERAGE CDEF:a=ao,1024,* 
AREA:a#95B8DB:"CPool in bytes"  GPRINT:a:LAST:"Current\\:%8.2lf %s" 
GPRINT:a:AVERAGE:"Average\\:%8.2lf %s" GPRINT:a:MAX:"Maximum\\:%8.2lf %s\\n" > 
graph.png
(process:14825): Pango-CRITICAL **: pango_context_load_font: assertion 
`pango_font_description_get_family (desc) != NULL' failed

(process:14825): Pango-CRITICAL **: pango_context_load_font: assertion 
`pango_font_description_get_family (desc) != NULL' failed
$ file graph.png 
graph.png: PNG image, 687 x 180, 8-bit/color RGBA, non-interlaced

So I wonder why the image doesn't occur in the webinterface. Does
anybody have similar issues?

greetings,
 jonas
