It seems most likely that there was an update that broke some things for you. The solution is to run arbtt-recover, then take the capture.log and rename it to something else (that is, back it up instead of deleting it), then rename capture.log.recovered to capture.log.
@Joachim: The similar error I encountered was "arbtt-stats: Prelude.chr: bad argument: 1728640". When I used arbtt-recover, it gave me a lot of outputs like this: "Failed to read value at position 6811645: Unsupported TimeLogEntry version tag 112" Does this help? Unfortunately, I don't remember if there was a recent upgrade.... But on the bright side, arbtt-recover saved all the data for me perfectly. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/931206 Title: Crash when running arbtt-dump or arbtt-stats To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/arbtt/+bug/931206/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
