File, by Mark Huot bug?

http://ellislab.com/forums/viewthread/103029/

If i comment out line 1272, everything works like it should.

$tagdata = preg_replace('/'.LD.$field_name.'(.*?)'.RD.'(.*?)'.LD.SLASH.$field_name.RD.'/s', '', $tagdata);

So, i leave it commented out, unless some bugs appear.

Maybe someone can shed some light on this issue?
