System Information
Kubuntu 18.04 - GTX 960

Blender Version
Broken: f22385f28e

Short description of error
This is a well-known scene that was used by someone on YouTube to demonstrate OpenSubdiv operation when it was released (the scene does not use OpenSubdiv anyway):

This is the crash log that I get:

OK, so nlastrip_evaluate_controls() creates PointerRNA with NULL ID here -- thats why strip_ptr.id.data is NULL (which wont play nice with animsys_write_orig_anim_rna())

That leads to crash:

P808 prevents the crash and seems to survive, but this is probably something @Sergey should check?

Another thing I noticed is that you get an assert when reloading trusted (opening with "Trusted Source" is not a problem -- reloading is... as well as opening any other file after this one...)
But that is probably something @mont29 knows more about? Should we open a separate report for this?

Another thing I noticed is that you get an assert when **reloading** trusted (opening with "Trusted Source" is not a problem -- reloading is... as well as opening any other file after this one...) But that is probably something @mont29 knows more about? Should we open a separate report for this? ``` 1 raise 0x7ffff1c93eab 2 abort 0x7ffff1c7e5b9 3 id_us_min library.c 247 0x28b5987 4 BKE_nlastrip_free nla.c 95 0x292ae90 5 BKE_nlatrack_free nla.c 128 0x292af2b 6 BKE_nla_tracks_free nla.c 152 0x292afb8 7 BKE_animdata_free anim_sys.c 249 0x27cf4f6 8 BKE_object_free object.c 558 0x294233e 9 BKE_libblock_free_datablock library_remap.c 710 0x28d0943 10 DEG::deg_free_copy_on_write_datablock deg_eval_copy_on_write.cc 1004 0x2d45404 11 DEG::IDDepsNode::destroy deg_node_id.cc 161 0x2d4ac5b 12 DEG::Depsgraph::clear_id_nodes_conditional(std::function<bool (ID_Type)> const&) depsgraph.cc 345 0x2d17566 13 DEG::Depsgraph::clear_id_nodes depsgraph.cc 356 0x2d17613 14 DEG::Depsgraph::~Depsgraph depsgraph.cc 108 0x2d16c56 15 DEG_graph_free depsgraph.cc 577 0x2d18193 16 depsgraph_key_value_free scene.c 2057 0x29aab70 17 ghash_free_cb BLI_ghash.c 650 0x2c91189 18 BLI_ghash_free BLI_ghash.c 1016 0x2c92a05 19 BKE_scene_free_depsgraph_hash scene.c 2079 0x29aac12 20 BKE_scene_free_ex scene.c 500 0x29a6e22 21 BKE_libblock_free_datablock library_remap.c 704 0x28d0921 22 BKE_libblock_free_ex library_remap.c 928 0x28d0f58 23 BKE_main_free library.c 1548 0x28bc903 24 BKE_blender_globals_clear blender.c 149 0x27e1ec7 25 setup_app_data blendfile.c 235 0x27e38ee 26 BKE_blendfile_read blendfile.c 402 0x27e3edf 27 WM_file_read wm_files.c 594 0x1a11439 28 wm_file_read_opwrap wm_files.c 1818 0x1a14014 29 wm_revert_mainfile_exec wm_files.c 1982 0x1a14693 30 wm_operator_invoke wm_event_system.c 1333 0x1a08620 31 wm_operator_call_internal wm_event_system.c 1530 0x1a08ca9 32 WM_operator_name_call_ptr wm_event_system.c 1578 0x1a08ecc 33 ui_apply_but_funcs_after interface_handlers.c 767 0x1d24fff 34 ui_popup_handler interface_handlers.c 9877 0x1d3d118 35 wm_handler_ui_call wm_event_system.c 569 0x1a065f9 36 wm_handlers_do_intern wm_event_system.c 2386 0x1a0afc3 37 wm_handlers_do wm_event_system.c 2619 0x1a0b8dc 38 wm_event_do_handlers wm_event_system.c 2988 0x1a0cab8 39 WM_main wm.c 412 0x1a020ce 40 main creator.c 525 0x19fceec ```
