c.f. https://pagure.io/fedora-rust/cargo2rpm/issue/7
Looks like cargo2rpm crashes but does not fail the build - possibly because it only prints the backtrace and error message to stderr, but no "invalid" output to stdout.
It looks like this is due to uncaught exceptions in cargo2rpm's main function.
Should be fixed in version 0.1.11.
