I was not getting location of parse error and inspecting `err` object (https://github.com/rubenv/angular-gettext-tools/blob/7a03fac03a1c6540cf2b2abe83849750cf58f621/lib/extract.js#L223) revealed it has `loc` attribute – holding both line and column of parse error – instead of `lineNumber` and `column` properties used currently.
