Cool, I know how to fix this now, thank you!
This is now fixed in upstream PhysicsFS here for the 3.0 branch:
https://hg.icculus.org/icculus/physfs/rev/c17f025e7a92
...and here for the default (what will eventually become an unstable
3.1.0) branch...
https://hg.icculus.org/icculus/physfs/rev/8b3cc36531c6
PhysicsFS versions before 3.0.0 do not have this issue.
This fix will be in 3.0.2, as a minor bugfix update, which is coming
sooner or later.
My (untested) belief is that this will resolve the Neverball issue, and
we can probably close this bug report now. Thanks for tolerating me
abusing Debian's bug tracker like this! :)
