Well, the message is pretty clear, the error is in the 'read', in child.

Because you trapped INT, so you removed the default action of terminating the
script.

This seems to be a run-parts issue. I was able to reproduce it without much
cruft, like this:

address@hidden ~ % run-parts t   
+ read x
^C++ echo int
int

t/s: line 4: read error: 0: Input/output error                                  
                                                        
address@hidden ~ % cat t/s
#!/bin/bash
trap 'echo int' INT
set -x
read x

So, for some reason, run-parts does something that read doesn't like. The
problem is that I can't strace/ltrace it, because when I do that, the problem
disappears.

You might want to reconsider your scripts also.
