PS: I'm Using Slackware 12, but all my packages are upgraded from Slackware 13.17.

After hours trying to solve this problem, i decide to reinstall pango and cairo.

I'm using Slackware, then i typed on my terminal slackpkg reinstall cairo

The cairo-1.10.2-i486-2 was reinstalled.

After all i chose Overwrite all old config files:

Some packages had new configuration files installed.
You have four choices:

(K)eep the old files and consider .new files later

(O)verwrite all old files with the new ones. The
old files will be stored with the suffix .orig

(R)emove all .new files

(P)rompt K, O, R selection for every single file

What do you want (K/O/R/P)?

The same thing was done with pango.

After that, my cacti is fine.
