Hi,

I have no clue how this could happen (but yeay, shit happens sometimes).

Bitwarden_rs version 1.9.0 on Debian 9.
~15 users using it flowlessly for 6 months
suddenly 1 of them tells me he is missing some organization shared passwords in its local synchronized vault (browser extension)

digging it:

he can connect to the web interface, but has no passwords and is not part of the org
browser extension parameters -> synchronize is broken
logs show this backtrace:

thread '<unnamed>' panicked at 'called `Result::unwrap()` on an `Err` value: Error("EOF while parsing a value", line: 1, column: 0)', src/libcore/result.rs:999:5
note: Some details are omitted, run with `RUST_BACKTRACE=full` for a verbose backtrace.

found out that this user had one cipher with sqlite3 data column empty
resolution: delete from ciphers where data='';

I think that was solved for 1.10 actually, you should consider updating.

If it happens again, try setting the environment variable RUST_BACKTRACE=full before launching the server to get a more detailed report.
