$ gpg --import facebook.asc
gpg: key 0x2F3898CEDEE958CF: public key "Facebook, Inc." imported
gpg: Total number processed: 1
gpg: imported: 1
gpg: signal Segmentation fault caught ... exiting
Segmentation fault: 11
After that, gpg will always throw "gpg: signal Segmentation fault caught ... exiting"
until I remove trustdb.gpg which will solve the issue (losing all trust information).
Using OS X El Capitan 10.11.5 (15F34) and gpg (GnuPG) 2.1.12 with the attached file.
