TileMill hangs if line-dasharray is set to 0

I was trying to set line-dasharray to its default value (manual says 'none'), so I did

 line-dasharray:none;

but nothing happened.

Then I set

 line-dasharray:0;

and the tilemill-tile process kicks CPU usage to 100% and rendering no longer happens until restart.
I can reproduce it every time.

Using Ubuntu 11.10, 64-bit.

   hi tilusnet,

   the manual says 'none' because for a solid line, a dash array is null. to get rid of you dash array, simply delete the selector.

   line-dash-array accepts two or more integers: at least one defining the length of the line segment, and one defining the length of the break between line segments.

   to see line-dash-array in action, try something like

   line-dash-array: 4,6;

   hi Ian,

   Finally I simulated a revert to the default 'solid' line by setting

   line-dasharray:1,0;
   

   I cannot delete the 'parent' selector because it is needed by other subsequent blocks.

   So to summarise my points here:

   1. there's no way to revert line-dasharray to its default value programmatically, unless simulated with the example above
   2. tilemill crashes if you provide unexpectedly formatted values, e.g. "0"

   In any case I am okay with my workaround, if you want take my points as suggestions for improvements.

   Thanks.

   Hey tilus,

   Thanks for reporting this - I've filed it as a ticket in Carto and will take a look at fixing the underlying issue.

   Tom
