Unknown bit assertion failed

[valentin-ricard]

Reproduction steps:

• Open a previously working RM file (used Lines_v2.rm in this repository)
• Using the desktop app, open the file
• Double click to create a node for writing
• Do not write text, and exit the editor

If this cannot be reproduced, here is a .rm file with the unknown bit different from 0.
(zipped the file due to github not supporting .rm files)

@valentin-ricard thanks for the example file. Should now be able to parse without error with dfbdae5.

A new CRDT id has been added to the Line scene item; not sure what it means, currently ignored.
