kfmclient format strings issues

[KF <dotslash () snosoft com>]

I have no clue how kfmclient is used...can anyone think of a situation
where this would be an issue? Is it called by any suids?

[d0tslash@linux /tmp]$ kfmclient %x,%x,%x,%x,%x,%x
Xlib:  extension "RENDER" missing on display ":0.0".
Syntax Error: Unknown command
