Qt Appimage crash reporting missing file when open file dialog (packed using linuxdeployqt)

[ychclone]

Hi, I've packaged my Qt application using linuxdeployqt:

https://github.com/ychclone/blink/tree/master/blinkAppImage

But it crashes when it open open dialog:

`(Blink-x86_64.AppImage:16591): Gtk-WARNING **: 10:37:40.688: Could not load a pixbuf from icon theme.
This may indicate that pixbuf loaders or the mime database could not be found.
**
Gtk:ERROR:../../../../gtk/gtkiconhelper.c:494:ensure_surface_for_gicon: assertion failed (error == NULL): Failed to load /usr/share/icons/Yaru/16x16/status/image-missing.png: Unrecognized image file format (gdk-pixbuf-error-quark, 3)
Bail out! Gtk:ERROR:../../../../gtk/gtkiconhelper.c:494:ensure_surface_for_gicon: assertion failed (error == NULL): Failed to load /usr/share/icons/Yaru/16x16/status/image-missing.png: Unrecognized image file format (gdk-pixbuf-error-quark, 3)
Aborted (core dumped)

How do I include the missing file in the AppImage? Or could linuxdeployqt include it automatically?
I'm using Ubuntu 20 to run linuxdeployqt

It crashes when it open file dialog

Strangely this error seems Gtk related.
Are you deploying some Qt plugins that are usingGtk?

[ychclone]

No, i'm only using widget, network, xml in the pro file. The program doesn't crash when it starts. It only crash when it load a file open dialog. Please see below the qmake project file:

`TEMPLATE = app

Wonder what is giving the Gtk:ERROR then.

Hi, I'd like to reproduce this but unfortunately there is no AppImage for download at https://github.com/ychclone/blink/releases.

[ychclone]

Hi, there's AppImage download in sourceforge:

https://sourceforge.net/projects/blink-code-search/files/1.9.1/

[probonopd]

Does not crash on my system when opening the file open dialog:

On my system there is no Gtk installed.

[probonopd]

The culprit is most likely that you are shipping Qt Gtk integration. Please try this:

./Blink-x86_64.AppImage --appimage-extract
./squashfs-root/AppRun # try it, it will crash at the file open dialog
rm squashfs-root/usr/lib/libgtk-3.so.0
rm squashfs-root/usr/plugins/platformthemes/libqgtk3.so
./squashfs-root/AppRun # try it, it will no longer crash at the file open dialog

So make sure your AppDir does NOT include

usr/lib/libgtk-3.so.0
usr/plugins/platformthemes/libqgtk3.so

You might get away with just removing libgtk-3.so.0 and leaving `libqgtk3.so``, but ymmv.

[ychclone]

How can I exclude libgtk-3.so.0 in the build? I'm just using the directory below for the build:
https://github.com/ychclone/blink/tree/master/blinkAppImage

And the following .pro file for the build:
https://github.com/ychclone/blink/blob/master/blink.pro

And the following command:
~/linuxdeployqt-continuous-x86_64.AppImage blinkAppImage/usr/share/applications/blink.desktop -verbose=2 -appimage -extra-plugins=iconengines,platformthemes/libqgtk3.so

[probonopd]

Leave away the ,platformthemes/libqgtk3.so

[ychclone]

Hi, it still crash after removing ,platformthemes/libqgtk3.so

[probonopd]

OK, so you most likely still have remnants of Gtk in your AppImage... can you check whether your AppImage does NOT include

usr/lib/libgtk-3.so.0
usr/plugins/platformthemes/libqgtk3.so

for sure?
