mas: segmentation fault: mas list

For the folks that have this, do you have a macOS installer downloaded? I think that was my problem. When I attempted to run mas list, this is what I got:

$ mas list                                                                                                                                                                      (254ms)

When I compiled from source and ran it, I got this (notice what’s below Pastebot):

So my guess is that the macOS installers (or possibly other apps?) don’t have a product.itemIdentifier and we get a segmentation fault.

I could use “mas list” again on High Sierra 10.13.1 after explicitely uninstalling mas via “brew uninstall mas” followed by a “brew install mas” and deleting the “Install macOS High Sierra” App from Applications. Prior to that, I also got a segmentation violation. I hope that this can help you as well bridging the gap until someone takes care of an update of this (beloved and still very useful) project…

Bam! I had this very same issueSegmentation fault: 11 and after I uninstalled my macOS Sierra installer the segmentation fault error was resolved. Hat tip to @wesbaker for the easy fix.

$ sw_vers
ProductName:	Mac OS X
ProductVersion:	10.12.6
BuildVersion:	16G1036

$ mas version
1.3.1

Sure enough, when I delete the installer, mas list works like before.
