Invalid byte sequence in US-ASCII

[ebongso]

After replacing the 'environment.upload_recipes' line with the 'environment.tar_and_upload_recipes_in_cookbooks_dir' line in the cli.rb (following the solution by jgross/akatz/infused), it gives me:
.....invalid byte sequence in US-ASCII
Environment is rebuilding...
.invalid byte sequence in US-ASCII
.invalid byte sequence in US-ASCII
.invalid byte sequence in US-ASCII
Jenkins is starting...
.....invalid byte sequence in US-ASCII
.invalid byte sequence in US-ASCII
.invalid byte sequence in US-ASCII
.invalid byte sequence in US-ASCII

This ".invalid byte sequence in US-ASCII" line goes to an infinite loop.
The engineyard version I use is 1.3.20
Could you please shed some light? Thank you.
