Doesn't crash in poppler-0.57.
I bisect: commit 3c29ded4bee5eadb829ed46af2ec92be57b0077b
Make Object free itself on init and destruction
Will make for a *much* easier way to code.
Patches with more std::move coming on top.
Most things seem to work though i'm pretty sure some things are broken.
NEEDS TESTING</pre>
