Thunderbird-60.0 on leap crashes at startup with my profile Thunderbird-52.9 ok

Hello

Upgraded to MozillaThunderbird-60.0-lp150.3.14.1.x86_64. Now it crashes with my profile.
New profile startup ok, it’s not a problem of pluggins
Downgrading to old one MozillaThunderbird-52.9.0-lp150.3.8.1.x86_64.rpm startup again without any problems.
What files should I delete without modifing my configuration (like global-messages-db.sqlite)
How can I turn on debugging to help?

No one crashing new thunderbird?

don’t delete anything
the first thing to do is back up your thunderbird profile you can use an addon like import export tools
https://addons.thunderbird.net/en-US/thunderbird/addon/importexporttools/
although the thunderbird developers wanted to keep the addon framework alive the fact that tbird 60 is based on Firefox 60 means a lot of old addond don’t work it could all be an old addon you have installed disable installed addons and try again
to see what’s going on start thunderbird from a console window and see the output messages
as far as I know thunderbird 60 is stable and shouldn’t crash
