Call to undefined function shiny_preprocess_html()

I'm running into that as well. The problem can be reproduced as follows:

cd /tmp
git clone --branch 7.x-2.x http://git.drupal.org/project/commerce_kickstart.git
cd commerce_kickstart
./scripts/build.sh /var/www/my-site

Then try to install the site from the browser. This will blow up with the following stack-trace:

PHP Fatal error:  Call to undefined function shiny_preprocess_html() in [...]/profiles/commerce_kickstart/themes/commerce_kickstart_admin/template.php on line 12

Examining the distribution freshly built from git with some releases I downloaded from the project page, I found that when building from git, shiny seems to be installed in the wrong place:

$ find commerce_kickstart-7.x-2.x-* -name shiny
commerce_kickstart-7.x-2.x-dev/profiles/commerce_kickstart/themes/contrib/shiny
commerce_kickstart-7.x-2.x-git/profiles/commerce_kickstart/modules/contrib/shiny

This is an issue with Drush 7.1. It places theme's in the module directory because it can't figure out type for some reason.

Patch attached

PR: https://github.com/commerceguys/commerce_kickstart/pull/164

Fix is in. Will be out on next release, slated for November 19th.

Wow, thanks. Do you think that this issue should be filed with drush also? It feels like that's actually a regression over there.

It should be. However I have been meaning to follow up on that for a long time and haven't. It's best to shiv it here or else queue will fill up with bug/support requests.
