Connecting to a MySQL database over SSH tunnel works when using Sequeler normally, but when using G_MESSAGES_DEBUG=all flatpak run com.github.alecaddd.sequeler it crashes with the output:

(Sequeler:2): GLib-DEBUG: 15:35:42.226: unsetenv() is not thread-safe and should not be used after threads are created
** (Sequeler:2): DEBUG: 15:35:44.282: PasswordManager.vala:50: Unable to fetch password in libsecret keyring for com.github.alecaddd.sequeler.19999
** (Sequeler:2): DEBUG: 15:35:44.282: ConnectionManager.vala:156: Opening tunnel 0x55615eb5b460
** (Sequeler:2): DEBUG: 15:35:44.283: ConnectionManager.vala:196: Socket params: 99.999.999.999 22
** (Sequeler:2): DEBUG: 15:35:44.529: ConnectionManager.vala:229: Authentication methods: publickey,password

This may be an issue with saving the connection itself. Trying to edit the connection also crashes:

Actually it seems this is reproducible when opening the app without debug messages as well so possibly a duplicate of #259
