Dear Maintainer,

when using reportbug in the terminal (text interface) it crashes. I just
started it with `-u gtk` right now which prevents the crash, but somehow
breaks copy&paste, therefore I will send yo the log in an follow up
email.

This must be caused by recent changes as I just used reportbug
successfully yesterday or the day before.

Best regards,
Martin

Will send report to Debian (per lsb_release).
