Both konsole (CTRL-Shift-P), and KWrite (via the File->Print menu item) exhibited this behaviour for me. I assume others do as well. Reproducible: Always

Don't you get a crashdump?
I rebuilt konsole, qtprintsupport, qtwidgets, and qtcore without optimization and with debug symbols to make this BT more useful. Let me know if this isn't enough and I can go deeper.

Looks like someone upstream hit it and fixed it, have a look at: https://code.qt.io/cgit/qt/qtbase.git/commit/src/printsupport/dialogs/qprintdialog_unix.cpp?id=2ad3348031d8a622374920eac5bdd8fb9ecefcd7 I'll test this patch presently and if it fixes, it seems simple enough to cherry pick?
Patch works for me here, applied against dev-qt/qtprintsupport-5.13.2 on stable amd64. Issue is gone for me.
