This seems to be 100% reproducible:
1. Run 'evince some.pdf'
2. Close lid (suspend)
3. Open lid (resume)
4. Unlock screen
5. CPU goes to 100%
6. 3-4 minutes later evince crashes anyway.
It sometimes happens instantly, with:

and sometimes takes several minutes before a SEGV.
Various things seem to be corrupt and pointing at the wrong places
print *be.geis.devices.device_store
$27 = (GeisDevice) 0x73
print be.geis.devices.device_store.ref_count
Cannot access memory at address 0x73
Presumably it's attempting to hold and retain access to a resource that
has been free()d or otherwise disappeared during suspend.
