Comment 3 for bug 1130751

http://hg.five-ten-sg.com/libpst/rev/6abc3054cba2 in 0.6.67 must probably fix this:

libpst

changeset 358:6abc3054cba2

From Jeffrey Morlan:

If a readpst child process fails with a nonzero status code for
whatever reason (killed, segfault, out-of-memory, ...) the parent
process will continue and likely end up exiting with status 0,
tricking the caller into thinking readpst was successful when it was
not.
