gEDA-dev: Another autosave crash....

[Peter Clifton]

Can people try to repeat this on CVS head and the latest release for me.

Steps _I_ took to trigger the bug (I did it twice this way, but its not
always reproducable).

1. Start gschem
2. Place a few components
3. Close schemetic page
4. Click "Discard changes" when prompted at the save dialog
5. Place a few components on the new page
6. Wait for autosave crash.


I'm getting the following backtrace:

Program received signal SIGSEGV, Segmentation fault.

(gdb) print toplevel
$1 = (TOPLEVEL *) 0x825a800
(gdb) print toplevel->page_head
$2 = (PAGE *) 0xffff
(gdb)


I hope we can track down a way to reproduce this, as that should very
quickly lead to a fix.
