I took your suggestion on starting in a terminal window. Thanks, got this:
(glade:8914): Gdk-WARNING **: 11:36:37.759: …/…/…/…/…/gdk/x11/gdkwindow-x11.c:5576 drawable is not a native X11 window
(glade:8914): Gdk-ERROR **: 11:36:37.760: The program ‘glade’ received an X Window System error.
This probably reflects a bug in the program.
The error was ‘BadWindow (invalid Window parameter)’.
(Details: serial 16497 error_code 3 request_code 20 (core protocol) minor_code 0)
(Note to programmers: normally, X errors are reported asynchronously;
that is, you will receive the error a while after causing it.
To debug your program, run it with the GDK_SYNCHRONIZE environment
variable to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error() function.)
Trace/breakpoint trap (core dumped)
Also what mechanism do I use to find the name and location of the crash file. Thanks
