SUMMARY

Gcompris crashes repeatably when playing the window wiping mouse game.


STEPS TO REPRODUCE
1. start gcompris, select mouse games, select window wipe game
2. play game, at level 1
3. keep wiping windows, it crashes eventually; sometimes takes a few goes

OBSERVED RESULT

We get a segfault, under gdb the following output:

[New Thread 0x7fff9dd22700 (LWP 20331)]
[New Thread 0x7fffd0b60700 (LWP 20332)]

EXPECTED RESULT

Don't segfault, let us wipe lots of windows, yay! Way to go! Awesome!

ADDITIONAL INFORMATION

Happy to help with repeating the crash, have repeated about 5 times; varies how long it takes but it might need one to change level repeatedly first, not entirely sure.

Hi,

you are using the old Gtk+ version (that is no more maintained since more 3 years) not the actual Qt version.
Which OS are you using? Can you try installing the gcompris-qt package if it exists which corresponds to the actual maintained version
