Downloading FlashFirebug extension from webstore gives "Manifest file is invalid."

[O-Minds]

Hello,

I got a report from my users that they're getting "Manifest file is invalid" when they try to install from my extension from the webstore. I tested it on Chrome 23+ and got the error.

When I loaded the unpacked extension, it worked fine. I felt somewhat puzzled and decided to repackage (assuming on-line version is somehow corrupt). So I uploaded a new version (4.66). But I'm still getting the same behavior, webstore version gives me "manifest file is invalid" and unpacked version is working fine.

Any help appreciated!

Fixed by uploading the ZIP file from another folder on my machine (with a shorter path!). Can you believe it? 

Thanks!
