This seems to happen in Qt's accessibility internals. Does the crash also happen with the latest appimage (3.2.0-beta.2)? https://download.kde.org/unstable/krita/3.2.0-beta.2/
Nope. It doesn't crash with krita-3.2.0-beta.2-x86_64.appimage.
Okay, then there isn't anything I can do, I'm afraid. It's an issue in the combination of Qt and at-spi -- not a bug in Krita.
Okay, I will try to report it in the Debian bug tracker. Thank you for the investigation.
