Hello
After running ubuntu-bug in terminal i've seen this:

ubuntu@ubuntu:~$ ubuntu-bug ubiquity
ERROR: hook /usr/share/apport/package-hooks//source_ubiquity.py crashed:

Is there actually a file /var/log/installer/syslog on the system you were running ubuntu-bug ubiquity on? Thanks in advance.

Hello Brian
No, I'm sorry but that I've reused that disk for another installation test
Thanks

I was able to recreate this by removing my syslog file in /var/log/installer so it seems the ubiquity source package hook should ensure the file exists before try to search it.

The problematic part looks to be the following (particularly the if statement):

    if os.access(f, os.R_OK):
        report[ident] = (f,)
    else:
        apport.hookutils.attach_root_command_outputs(report,
            {ident: "cat '%s'" % f})

Right, "(f,)" just attaches a file reference, so you can't directly grep it in the same hook. So your solution with reading the file contents looks fine, thanks!
