Bug Description

Binary package hint: byobu

I was running 'ssh-agent byobu' over ssh. Lost my ssh connection, reconnected, did 'ssh-agent byobu' again, which hung for awhile. Killed that, restarted again, and it gave me a fresh session, whereupon I noticed this in syslog:

May 26 10:10:36 sergelap kernel: [658538.322656] screen[21148]: segfault at 0 ip 000000000042bce0 sp 00007fffa3a78f10 error 4 in screen[400000+58000]

I'm pretty sure this is related to the new "layout" configuration options in Natty's byobu.

I think this might be fixed by:

Hi Dustin,

Because I committed[1] the appropriate "LP: 788670" string to the
changelog of the upcoming screen package for Debian which will once
wander to Ubuntu, too.

  [1] http://anonscm.debian.org/gitweb/?p=collab-maint/screen.git;a=commitdiff;h=63079b9a3ae5cced3ce8c60125774318b9fbd2f6

Why did you change it to Fix Released for screen in Ubuntu? There's
just a bugfix released in a package for byobu, but not yet for screen.

Or do you not regards this as a bug which should be fixed in screen,
too? If so, then why is it listed as such?

  Regards, Axel
