gEDA-user: GTK PCB crashes with losing the data

[Karel Kulhavy <clock@xxxxxxxxxxxxx>]

I was drawing a schematic. Suddely PCB crashed with the following errors
and destroyed my unsaved work. The windowmanager is fvwm. pcb-bin:
20050609

I don't know whether the "** Message: GotoError: ChangeGroupVisibility
(GetLayerNumber" errors were produced during the crash or during
previous work.

clock@kestrel:~/creat/ronja/trunk/schematics$ pcb twister2.pcb
** Message: GotoError: ChangeGroupVisibility (GetLayerNumber
** Message: GotoError: ChangeGroupVisibility (GetLayerNumber
** Message: GotoError: ChangeGroupVisibility (GetLayerNumber
** Message: GotoError: ChangeGroupVisibility (GetLayerNumber
The program 'pcb-bin' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadRequest (invalid request code or no such operation)'.
  (Details: serial 25054107 error_code 1 request_code 0 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 --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error()
function.)
