Well, it's working now. The framework had been set to ubuntu-sdk-15.04. This did produce an error on build, but I ignored it. I just tried setting it to ubuntu-sdk-14.10, and it worked. Then I reset it to 15.04, and it still works.
I don't know what to make of this. If you want to close the bug, that's fine. But I'm also happy to run further diagnostics if they would help.
