Since 22.10 ubuntu update, unread mails are no more reported

System AMD64 Ryzen
8GB RAM
Ubuntu 22.10 Beta / MATE desktop
Thunderbird 102.3.2
Birdtray version 1.9.0 compiled at Sep 30 2021 18:54:11 using Qt 5.15.2.

Since the update toward 22.10, birdtray does not report any unread mail.

Log console inside the application lead to Qt crash :

QObject::killTimer: Timers cannot be stopped from another thread
qt.qpa.xcb: QXcbConnection: XCB error: 3 (BadWindow), sequence: 4247, resource id: 12983066, major code: 40 (TranslateCoords), minor code: 0

Erreur de segmentation (core dumped)

Launching birdtray with log on file, we can see that birdtray detects accesses to mail boxes,
Here I'm toggling one mail from read to unread with no detection :
