Wayland (Fedora 25) causes Segfault?

[bit4man]

I'm getting segfaults after upgrading to F25 when I launch pronterface. I do not get Pronterface loaded at all and abrt refuses to post a BZ since no frame or threads are found in the dump. From retrace it seems the issue is caused by "libwayland-client.so.0". I need advice on how to provide the correct dump/data on this.

If you run Pronterface with:

GDK_BACKEND=x11 pronterface

Is the problem gone? We have had some crashes with wxPython apps on Wayland, so if this fixes the issue, I will make it the default in Fedora.

I don't have access to the actual workstation today. However, I did a ssh -X (X11 forwarding) to the box and that works. Which is why I concluded it was Wayland. Sorry for not stating that initially.

@hroncok confirmed. Setting GDK_BACKEND=x11 fixes the issue (or bypasses it to be more specific). Thanks for the tip!

@hroncok Great! That's fixed my problem - thank you very much indeed, Hroncok.
