[5.4.0] segfault on Open File(s) menu

[oyvindaabling]

Cura Version

5.4.0

Operating System

Linux Debian 12.1

Printer

Artillery Sidewinder X1 v4

Reproduction steps

Start UltiMaker-Cura-5.4.0-linux-modern.AppImage, select File -> Open File(s) ..., or press Ctrl-O.

The legacy Linux version (UltiMaker-Cura-5.4.0-linux.AppImage) on a Debian 11.6 shows the same behaviour.

Cura complains in the logfile (attached) that:
WARNING - [MainThread] UM.Qt.QtApplication.__onQmlWarning [444]: file:///tmp/.mount_UltiMab2t2DI/share/cura/resources/qml/Cura.qml:624:5: QML FileDialog: Failed to load non-native FileDialog implementation:
qrc:/qt-project.org/imports/QtQuick/Dialogs/quickimpl/qml/FileDialog.qml:4 module "Qt.labs.folderlistmodel" is not installed

Actual results

Cura segfaults with these messages:

QFSFileEngine::open: No file name specified
/tmp/.mount_UltiMadZb8FI/AppRun: line 25: 17528 Segmentation fault $scriptdir/UltiMaker-Cura "$@"

If I instead choose File -> Open Recent -> xyz.stl, it works fine - the model loads, and I can slice, preview, save, etc.

Expected results

The "Open File(s)" file selection popup window should appear.

I want to report having the same bug.

Cura version: 5.4.0-1

Printer: Artillery Sidewinder X1

OS: Arch Linux 6.5.5arch1-1

Thank you for your time.

The way around it is to open it up from the command line or file browser... https://aur.archlinux.org/packages/cura-bin

I found a workaround. Posted about it here: #16335 (comment)

./UltiMaker-Cura-5.4.0-linux-modern.AppImage -platformtheme gtk3

[Rushmore75]

Same Issue, slightly different error codes:

/usr/bin/cura5: line 5:  7483 Segmentation fault      LD_PRELOAD=/usr/lib/libstdc++.so.6 QT_QPA_PLATFORMTHEME=xdgdesktopportal QT_QPA_PLATAFORM=xdgdesktopportal ./UltiMaker-Cura $@

(@geraldnilles's workaround works tho <3)

Issue still present in 5.6.0

[AdamScherlis]

Same issue in aur/cura-bin 5.6.0-1 on EndeavourOS 2023.11.17 (KDE):

/usr/bin/cura: line 3: 32254 Segmentation fault (core dumped) /opt/ultimaker-cura/AppRun "$@"

@geraldnilles trick worked for me too! (as cura -platformtheme gtk3)

[dj-foxxy]

On Arch Linux updated today cura -platformtheme gtk3 worked.

Worth noting that, at least for me, the Save Project... and Export... dialogs DO work.
