Fail to create an environment variable

Hi there,

I have this environment variable created from the web interface: foo='* 23 * * * *'

When I log the variable in a console I get a strange output:
'* */6 gulpfile.js node_modules npm-install.sh package.json README.md circle.yml gulpfile.js node_modules npm-install.sh package.json README.md circle.yml gulpfile.js node_modules npm-install.sh package.json README.md circle.yml*'

Somehow the variable get merged with the names of the files from the repository.

Why this is happening? And what can I do to have the variable unmodified?

Thanks

Are there any news on this issue?
