Could you possibly let me know what file was in
/var/lib/schroot/session/, and if you have it, the contents?

Can you reproduce the problem again?  If so, could you take me through
the steps to cause a file to be left in the session directory.  A
file in there on its own shouldn't cause problems, and certainly not
a segfaulty.  Additionally, could you run schroot with the additional
options '-v --debug=notice' which should help track down where the
fault is.

If you have time, you could also install schroot-dbg and run schroot
(as root) in gdb.  Just run 'gdb /usr/bin/schroot' and then
'run -i -c A' and when it segfaults, type 'backtrace' to get a
detailed trace of where the fault occured.



Thanks,
Roger
