Package: thunderbird Version: 1:140.14.0esr-1~deb13u1 Severity: important Dear Maintainer,
after upgrading Thunderbird from 1:140.13.0esr-2~deb13u1 to 1:140.14.0esr-1~deb13u1, Thunderbird crashes reproducibly when performing drag-and-drop operations across application/window boundaries. The problem occurs, for example, in both of the following cases: 1. Dragging an e-mail message from Thunderbird to another application (Firefox in my test case). 2. Dragging an attachment from an e-mail in Thunderbird to the file manager. Thunderbird crashes as soon as the drag-and-drop operation is performed. The issue is reproducible in an XFCE desktop session running via XRDP using X11. Terminal output at the time of the crash includes: [GFX1-]: RenderCompositorSWGL failed mapping default framebuffer, no dt ExceptionHandler::GenerateDump minidump generation succeeded Exiting due to channel error. In one test the following additional graphics error was reported: Crash Annotation GraphicsCriticalError: |[C0][GFX1-]: CompositorBridgeChild receives IPC close with reason=AbnormalShutdown I performed the following tests with 1:140.14.0esr-1~deb13u1: * Normal mode: reproducible crash. * --safe-mode: reproducible crash. * MOZ_WEBRENDER=0: reproducible crash. * MOZ_DISABLE_RDD_SANDBOX=1 MOZ_WEBRENDER=0: reproducible crash. * XFWM compositing disabled: reproducible crash. Most importantly, I then downgraded only Thunderbird to: 1:140.13.0esr-2~deb13u1 using the previous Debian package from my local APT cache. With Thunderbird 140.13.0esr, the same drag-and-drop operations work normally and reproducibly without any crash. The upgrade from 140.13.0esr to 140.14.0esr therefore appears to introduce a regression affecting drag-and-drop in this X11/XFCE/XRDP environment. Environment: * Debian 13 (trixie) * XFCE * X11 * XRDP remote desktop session * amd64 * Thunderbird installed from the official Debian package * affected version: 1:140.14.0esr-1~deb13u1 * last known working version: 1:140.13.0esr-2~deb13u1 Thunderbird generated a minidump for every reproduced crash. I can provide the corresponding .dmp and .extra files if useful. For the time being I have downgraded Thunderbird to 140.13.0esr and placed the package on hold, as this restores working drag-and-drop. Please let me know if additional diagnostics, crash dumps, or tests are required.
