Unknown LC_CTYPE causes crash

[Dan Watkins]

command-not-found crashes when the LC_CTYPE is defined in the environment but is not installed. This can be seen via SSH which sets the LC_CTYPE.

$ env
TERM=xterm
SHELL=/bin/bash
<snip>
LANG=en_US.UTF-8
<snip>
LC_CTYPE=en_GB.UTF-8

$ foo
Sorry, command-not-found has crashed! Please file a bug report at:
https://bugs.launchpad.net/command-not-found/+filebug
Please include the following information with the report:

command-not-found version: 0.2.44

$ unset LC_CTYPE

$ foo
No command 'foo' found, did you mean:
 Command 'fio' from package 'fio' (universe)
 Command 'goo' from package 'goo' (universe)
 Command 'fop' from package 'fop' (main)
 Command 'fox' from package 'objcryst-fox' (universe)
 Command 'xoo' from package 'xoo' (universe)
 Command 'fgo' from package 'fgo' (universe)
 Command 'zoo' from package 'zoo' (universe)
foo: command not found

Steps to reproduce:

Run "LC_CTYPE=foo f"
