Delta Chat crashes on Android when switching mail server, old postfix dovecot, new stalwart

[dlukt]

see also stalwartlabs/stalwart#1292

• Android version: 14
• Device: S24 Ultra
• Delta Chat version: 1.54.3
• Expected behavior: not crashing
• Actual behavior: crashing
• Steps to reproduce the problem:
  log in with
  user dummy@icod.de
  pw 123123123
  at mailserverx.de
• Screenshots:
• Logs:

Since it crashes immediately when starting, I can't access any logs.

So to recap:

• moved an email domain and address from postfix/dovecot on 1 server to stalwart mail on another server.
• changed the mail server configuratin in delta chat
• saved and it crashes. Only happens with Stalwart Mailserver, not with Postfix and Dovecot.
  also cleared data and cache and started fresh with an empty Delta Chat.
  Postfix / Dovecot - no issues, Stalwart - crash

Update: also crashes on S10+

@dlukt thanks a lot for reporting, I transferred the issue since this is not a bug in the Android app, it also affects iOS etc.

account configuration succeeds but shortly afterwards core crashes constantly every time you open the app rendering Delta Chat unusable, the only way to recover is to turn off network and delete the profile, so the bug is while communicating with the IMAP server

That's the stack trace when running in the repl:

[dlukt]

The mailboxes have no quota and I'm guessing Stalwart therefore doesn't return a percentage used or 0 e.g. 145k of 0 which is 145000/0 = division by zero

[dlukt]

Thank you please let me know when I'm able to remove the mailbox so it doesn't potentially get abused.
That was btw very satisfying, pleasure communicating with you guys.

[adbenitez]

@dlukt there is a fix already at: chatmail/async-imap#116
so you can remove the account, thanks a lot for all the useful information and support to fix this issue!
