Negative value mistaken for an operator

[Nicolas Cadou]

Converting this valid CSS:

.test { margin: 0 auto -1px auto; }

Results in this (removing the negative sign works as expected):

Traceback (most recent call last):

Another one, probably related to the same problem:

.test { margin: 0 -1px -1px 0; }

Results in this:

invalid literal for float(): 0 -1px

BTW, is there a way to get the line number where an error happened?

Fixed in version 0.8.4

Thanks

Thanks! Works like a charm.

And I should add: that was fast :)
