Broken journal file crashes target-info

[lhaagsma]

While running target info against a debian/ubuntu target it encounters a ~~seemingly~~ broken journal file. This exception is unhandled and stops the execution of target-info entirely. So these are two bugs:

1. improve journal parsing
2. harden target-info so that it does not completely exit when encountering an error
