Receiving iron-router splash screen with standard-minifiers package

After update to Meteor 1.2 at some point I started to see Iron-Router error/splash screen in production mode (Organize your Meteor application.). After removing package by package I found that the reason is standard-minifiers.

First of all I tried to fix my less imports, but it doesn’t solve the problem (updated them with relative paths using {}/). I’m receiving few errors in console in the production mode (Tracker is not defined and ServiceConfiguration is not defined), but I’m not sure what should I do with them. In the dev mode everything works well and there is no exceptions in browser. Any ideas how should I debug such case?

Tried to reinstall meteor, rebuild app, remove all cache, but it didn’t help.

Here is a list of my current packages:
