Hi,
thank you for the report.

Can you give the exact Qt version (when launching GCompris, in the 'G' button, there should be slomething like "Using Qt version ...")?

Does the crash happen in other chess games and is it only these 2 moves that crashes?

I'll get a ubuntu vm with 18.10 to try to reproduce the issue.
Comment 2 Jazeix Johnny 2019-01-08 08:07:18 UTC 
I can reproduce, I installed a vm with kubuntu 18.10, gcompris-qt from package and it crashes in libQt5Qml
I'll debug it later.
Comment 3 Jazeix Johnny 2019-01-08 19:24:53 UTC 
Issue still there with latest master code
Comment 4 bce 2019-01-08 19:41:01 UTC 
It says : Qt 5.11.1

Such issue occurs on majority of chess move.
(i managed to do some moves on level 6 of "end of party")
Comment 5 Jazeix Johnny 2019-01-10 08:15:50 UTC 
It's a Qt bug,
it does not crash with Qt5.11.3 installed via Qt-online, but crashes with Qt5.11.1 and Qt5.11.2 from Qt-online.
I'll try to contact people from https://packages.ubuntu.com/cosmic/qt5-doc to know if/when they plan to update Qt in ubuntu.
Comment 7 Jazeix Johnny 2019-01-20 10:02:13 UTC 
A temporary workaround would be to use https://gcompris.net/downloads-fr.html#linux (you can install it in ~/gcompris_qt for example) and once the distribution has updated the Qt version, you'll just have to remove this folder.
Comment 8 Jazeix Johnny 2020-12-20 13:17:15 UTC 
It was caused by Qt5.11.1 or Qt5.11.2 which should not be used anymore by distributions.
