Complete freeze if breakpoint is placed in gtk signal handler
Submitted by Gunter Königsmann
Assigned to Wayland bug list
If you place a gdb breakpoint in in a signal handler of a wxGTK or GTK application (for example MathCtrl::OnPaint in wxMaxima) mouse, screen and keyboard completely freeze, if this event handler was triggered by a GUI event. The keyboard is physically working, still, and with a bit of luck one can switch from wayland to a text console and kill gdb from there - which returns the wayland session to a working order.
Don't know if that is a bug or if it is completely unavoidable so I would accept a "WONTFIX".
