[Touch-packages] [Bug 1838891] Re: qt5 applications crash when opening file chooser in gtk desktops
I just managed to reproduce the crash locally. Just before the crash, the following lines are printed to stderr: (AppImageLauncherSettings:27871): Gtk-WARNING **: 21:45:01.935: 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/Adwaita/16x16/status/image-missing.png: Fatal error reading PNG image file: bad parameters to zlib (gdk-pixbuf-error-quark, 0) I think most important part here is “bad parameters to zlib”. AppImageLauncher uses its own static zlib (lib/AppImageUpdate/lib/zsync2/lib/zlib/libzsync2_libz.a) which is incompatible with public zlib (/lib/x86_64-linux-gnu/libz.so.1) that GTK was compiled against. Recompiling AppImageLauncher with system zlib should help, but I haven’t found a way to do that. I suggest you to ask AppImageLauncher developer about that.

Ubuntu 18.04 qt5-gtk-platformtheme 5.9.5+dfsg-0ubuntu2.1 DE is Mate 1.20.0 It's X11, running with “-platform wayland” doesn't work: This application failed to start because it could not find or load the Qt platform plugin "wayland" in "". It happens with the thridparty app AppImageLauncher when I run "AppImageLauncher Settings": https://github.com/TheAssassin/AppImageLauncher The devs of AppImageLauncher said it's a Qt related issue and not an issue with their program. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to qtbase-opensource-src in Ubuntu. https://bugs.launchpad.net/bugs/1838891 Title: qt5 applications crash when opening file chooser in gtk desktops Status in qtbase-opensource-src package in Ubuntu: New Bug description: Issue is apparently related to qt5-gtk-platformtheme.

[Touch-packages] [Bug 1838891] Re: qt5 applications crash when opening file chooser in gtk desktops
Can you please specify some more details about this issue: 1) Which Ubuntu release are you using? 18.04 (Bionic), 19.04 (Disco), 19.10 (Eoan) or some other? 2) What is the version of Qt package? I.e. the output of “apt policy qt5-gtk-platformtheme”. 3) What desktop environment does this happen on? Is this X11 or Wayland? If Wayland, is Qt using XWayland or running natively (does this happen when you run app with “-platform wayland”)? 4) What applications does this happen with? If this happens with many applications please name a few, so that I can look for crash logs in our error tracker. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to qtbase-opensource-src in Ubuntu. https://bugs.launchpad.net/bugs/1838891 Title: qt5 applications crash when opening file chooser in gtk desktops Status in qtbase-opensource-src package in Ubuntu: New Bug description: Issue is apparently related to qt5-gtk-platformtheme.
