I think the signal is SIGPIPE (13, Broken pipe), Blackbox just terminates
without saving anything.
See man 7 signal:

Signal Value Action Comment
-----------------------------------------------------------------------
SIGPIPE 13 A Broken pipe: write to pipe with no readers
(....)
The letters in the "Action" column have the following
meanings:
A Default action is to terminate the process.

So blackbox could catch the signal.
CTL+ALT+BS is most times not a clean way to exit X or a Desktop
environment (not that I don't use it: I do CTL+ALT+BS then CTL+ALT+DEL to
quickly halt my machine).
In most cases the apps you run are not children of X, but is it like this:
startx
`--X
`--Blackbox
`--app1
`--app2
or:
xdm
`--X
`--xsession
`--Blackbox
`--app1
`--app2
[disclaimer:AFAIK].
Good luck!
