I don't know if it's really an issue.

This might be a bug.

The Dart team would greatly appreciate it if you would take a moment to report this problem at http://dartbug.com/new.
If you are comfortable with it, it would improve the chances of fixing any bug if you included the file file:///var/folders/zb/jmv5h59n4tg_r6lb56yf1w480000gn/T/initialize_from.dillm9NSTX/initialize_from.dill.gz in your error report, but be aware that this file includes your source code.
Either way, you should probably delete the file so it doesn't use unnecessary disk space.

Thank you for reporting this.
This is caused by the file we try to initialize from being empty. This can happen if for instance launching several instances working on the same file (e.g. one instance is overwriting the file while the other is reading it). As long as it doesn't happen all the time it's nothing to worry about.
I recently landed d8739b5 to make sure we don't even try to load when the file is empty, and this warning will thus be avoided.
