Comment 111 for bug 530605

The lock happens even with the target machine not responding to ping....

attempting connection with target IP powered off, gvfs started eating all cpu as usual.

gdb --pid=$PID
break auth_callback
c

just keep 'quiet' for a long period, after killing $PID it displays:

(gdb) break auth_callback
Breakpoint 1 at 0x409600: file gvfsbackendsmb.c, line 155.
(gdb) c
Continuing.

Program received signal SIGTERM, Terminated.
