Crash when attaching to screen

See original GitHub issue

Bug description

When attaching to a screen session with “screen -r” ConnectBot crashes. Seems that this is related to something specific that is shown on the currently active screen window. Attaching from a computer and changing the active window to something else removes the issue. But ConnectBot again crashes when changing back to that specific window.

Steps to reproduce

  1. Connect to my server with my credentials with a specific window active in a screen session
  2. screen -r
  3. ConnectBot restarts back to the Hosts-list

Expected behavior

Screen content shouldn’t crash ConnectBot

Android device

  • Device: Sony ZX2 Compact
  • OS: Android 9 52.0.A.3.126
  • ConnectBot Version: 1.9.5

Server information

  • OS: Ubuntu Linux 16.04
  • SSH Software and Version: OpenSSH_7.2p2 Ubuntu-4ubuntu2.6, OpenSSL 1.0.2g 1 Mar 2016

I have also a larger Logcat dump saved, but it will need some redacting before publication here.

Screen session

The active screen window causing this is still open in my screen session, but will naturally vanish in the next reboot. Any hints on how to save the state? The problematic window just has a bash command line with some history visible.

Seems to depend on terminal emulation type:

xterm-256color -> crash on long lines xterm-color -> crash on long lines xterm -> ok

I can confirm that. It stops crashing after changing terminal type to xterm. Android 9 (Samsung A40), ConnectBot 1.9.6.
