Error sending notification with tmux

[bjoernalbers]

I just got this error with Guard 2 (Guard 1.8 works fine):

10:58:48 - ERROR - Error sending notification with tmux: undefined method `to_sym' for nil:NilClass
10:58:48 - ERROR - Error sending notification with terminal_title: undefined method `to_sym' for nil:NilClass

Hello, I've pushed a commit to master so that debugging should be easier (backtraces are now displayed when in debug mode).

Could you try guard master in debug mode (in your Gemfile: gem 'guard', github: 'guard') and using one notifier at a time (in your Guardfile: notification :tmux first, then notification :terminal_title) and let us know what the errors and backtraces are?

Thanks in advance!

Tmux works fine for me. Can you show your Guardfile and .guard.rb if present?

@rymai I ran you backtrace patch against the given project but it couldn't reproduce the bug (same with guard 2.1 via RubyGems). Maybe a tmux hiccup? Anyway, sorry for the noise...

This is fixed in 2.2.1!
