I'd like to get to the bottom of those crashes. The underlying cause, is
that I didn't use Asynchronous IPC calls with DBus, and xgsch2pcb blocks
for a response its not going to get from PCB.

Then start PCB, do you get output like this:

method call sender=:1.30 -> dest=org.freedesktop.DBus
path=/org/freedesktop/DBus; interface=org.freedesktop.DBus; member=Hello
signal sender=org.freedesktop.DBus -> dest=(null destination)
path=/org/freedesktop/DBus; interface=org.freedesktop.DBus;
member=NameOwnerChanged
   string "org.seul.geda.pcb"
   string ""
   string ":1.30"
method call sender=:1.30 -> dest=org.freedesktop.DBus
path=/org/freedesktop/DBus; interface=org.freedesktop.DBus;
member=RequestName
   string "org.seul.geda.pcb"
   uint32 2

(:.... numbers will be different).


If this works, what do you get when using xgsch2pcb to open a layout?
(There may also be some spew when the open dialog is used (Gnome / Gnome
VFS I think).


If you're not on a distro which starts a dbus session bus for you at
login, try this:

dbus-launch /path/to/xgsch2pcb


Thanks for your patience in helping debug this.

Best wishes,
