When using emerge to find a fictitious package, portage attempts to iterate over a NoneType causing it to crash. This happens when the pretend flag is set. Reproducible: Always Steps to Reproduce: 1. run emerge -p fictitious_package 2. Observe crash 3. Actual Results: % emerge -p fictitious_package These are the packages that would be merged, in order: Calculating dependencies... done!
