assetic:dump fails with ".pull-right is undefined: line: 60"

Question

I was trying to install the glyphicons locally rather than pulling from the CDN (which had stopped displaying them, for reasons I didn't investigate). Now running assetic:dump results in an exception I have no idea how to fix:

me@server:/var/www/blah$ php app/console assetic:dump -vvv
Dumping all dev assets.
Debug mode is on.

Any advice is greatly appreciated!

Answer 1

Turns out it's a bug in lessphp: https://github.com/leafo/lessphp/pull/478

Currently the solution is change the version in composer.json to:

"require": {
    "leafo/lessphp": "dev-master#85bd4557920d5f4fcbf41beb621e91b842e3621b"
}

but obviously this is just temporary. Thanks to milka in #symfony on freenode!
