You can force it with:
QT_QPA_PLATFORMTHEME=gtk3 spectacle

However on Arch I cannot reproduce a crash on saving the screenshot:
spectacle 19.04.2-1
gtk3 1:3.24.10-1
qt5-base 5.13.0-7

Updated versions of KDE software probably doesn't make a difference here;
you'll need the latest version of Gtk.

Is there some way to force using Gtk's QPA plugin when launching Spectacle? I
could test it on Arch, maybe.

If it is reproducible, can you attach a gdb backtrace? Thanks :)

It is reproducible with 15.12.3; I tried to update yesterday but apparently
opensuse leap doesn't have a newer version yet.

Er... No, it's so long ago that I don't have a backtrace anymore. The relevant
commit is:L

BUG:338067 Workaround broken cliplboard in the the gtk file dialog

Krita hangs when it gets a signal from the application clipboard when
the user copies a string in the gtk-based file dialog. This hangs
somewhere deep in Qt, with a seemlingly endless loop in

QVariant QMimeDataPrivate::retrieveTypedData(const QString ,
QVariant::Type type) const

By blocking the clipboard's signals we avoid the hang.

Do you have a gdb backtrace?

Can you point to the exact commit that fixed this for Krita? I see a bunch of
changes at
https://phabricator.kde.org/diffusion/KRITA/history/master/libs/widgetutils/KoFileDialog.cpp

Finally Krita removed the native dialog in
https://phabricator.kde.org/rKRITAcfc4efaf01cc17e795dfcac972563d4095cbd02f in
attempt to solve bug 364864 (which it did not according to the comments?)
