Bug 405979 – In prefix branch, typo in data.py results in trace when UNIX group owner of prefix does not exist

• Status: RESOLVED FIXED
• Product: Portage Development

[Description Lucian Poston 2012-02-27 04:50:18 UTC]

Emerge crashes in prefixed portage when the group owning the prefix does not exist.

When connected to my VPN, groups are queried from ldap. I created the prefix while connected to VPN, so the prefix directory is owned by a group in ldap. When I disconnect from the VPN, the owning group does not exist as far a portage can tell.

In this situation, a typo in data.py causes emerge to crash.

Reproducible: Always

Steps to Reproduce:
1. Create gentoo prefix.
2. Remove group owning the prefix.
3. Run `emerge` to see crash
Actual Results:  
emerge crashes. See traceback.
