Bug#1014638: thunderbird: 1:102.0.1-1 update breaks unser interface - no accounts, emails are shown in main window

[Vincas Dargis]

I have reproduced issue on my Sid virtual machine. I've copied (pre-upgrade) profile from backup, upgraded Thunderbird 
and same issue appeared.

To fix I launched --safe-mode, and selected to reset toolbars and controls. I did not 
check "Disable all addons".
Sadly, --verbose did not produce anything useful to detect what's happening.
