the build logs for monkeysphere 0.43-3 on [sparc64](https://buildd.debian.org/status/fetch.php?pkg=monkeysphere&arch=sparc64&ver=0.43-3&stamp=1557526474&raw=0) [s390x](https://buildd.debian.org/status/fetch.php?pkg=monkeysphere&arch=s390x&ver=0.43-3&stamp=1557524452&raw=0) [ppc64](https://buildd.debian.org/status/fetch.php?pkg=monkeysphere&arch=ppc64&ver=0.43-3&stamp=1557526323&raw=0) show it failing with:
```
gpg: key generation failed: Invalid S-expression
```
This happens based on [this part of the test suite](https://salsa.debian.org/pkg-privacy-team/monkeysphere/blob/debian/master/tests/basic#L274) which invokes [gpg --generate-key](https://salsa.debian.org/pkg-privacy-team/monkeysphere/blob/master/src/share/mh/import_key#L97) with this input:
```
Key-Type: $keyType
Key-Grip: $keyGrip
Key-Usage: auth
Name-Real: $serviceName
%no-protection
%commit
```
the same test suite appears to work fine on the other builders, and i've seen the same test suite work fine on 32-bit big-endian powerpc architecture running 2.2.13 as well.
