segmentation fault, Qt app crash when XPS printer dialog is closed



  • Hello,

    I encountered a 100% crash when I tried closing "Microsoft XPS Document Writer" SAVE FILE dialog box.
    This is what I have:

    • a class to handle printer
    • an invokable function for QML app to print text

    Repro step:

    • set "Microsoft XPS Document Writer" as default printer on Windows control panel
    • run app
    • populate text and trigger printing
    • Microsoft XPS Document writer will ask for a save file location via dialog box
    • click cancel on the dialog box

    My OS: Win 10

    My Investigation so far:

    • No crash occurred when I use physical printer, regardless whether the printer is connected or not
    • Since I'm building QML app and my printing function is a "QINVOKABLE" function

    Any suggestion and help is really appreciated.

    Thank you

    Hi,

    What version of Qt are you using ?



  • @SGaist

    Hi, thanks for the reply. I'm still using Qt 5.5.0

    Can you test that against a more recent version to check it's still misbehaving ?
