It can also cause a crash.
Just for kicks, I tried
marko's filenames rule as a smartlist rule (I know, it is not intended to be a smartlist):
if(isequal([media type],audio,1),if(isequal([album artist (auto)], /(Multiple Artists/), 1),[track #] - [artist] - [name],[track #] - [name]),if(isequal([media type],image,1),if(isequal([type],album art,1),[album] /([keywords]/) ~ [dimensions],[name]),if(isequal([type],television,1),if(isequal([episode],unknown,8),[name],if(isequal([name],S0,8),Episode [Episode],[Episode] - [name])),if(isequal([type],movies,8),if(isequal([track #],00,8),[name],[name] #[track #]), if(isequal([type],music,8),[artist] - [name]if(isequal([duration],unknown,8),,/ /(Length - replace([duration],:,.)/)),[name]))
I pasted it in the rule box and pressed OK. It created a window that cannot be closed or canceled gracefully (see the attached screenshot). The only apparent way to get rid of it is to press the X button (top right). That causes an immediate, reproducible crash.
The last three lines of the log:
