gomuks crashes when exporting encryption keys

gomuks crashes when /export'ing encryption keys

When I run /export keys.txt

I get a fatal error and the following stack trace:

I tried to upgrade mautrix to fix this for no avail.

I don't really need to get this fixed. I just want to get all my encryption keys from gomuks. So if there is a workaround available, I'd like to hear.

I'm seeing a crash on key export too. Looks like a different stack trace though:

Same issue on my end. First I got this stacktrace:

In #gomuks:matrix.org @tulir mentioned this:

it might start working if you run DELETE FROM crypto_megolm_inbound_session WHERE session IS NULL; in ~/.local/share/gomuks/crypto.db

Which I tried, after which I got this:
