While using electric mode, inserting pair signs (e.g. brackets) causes the following error:
Symbol's value as variable is void: last-command-char
It is an issue of Emacs 24:
GNU Emacs 24.2.50.1 (x86_64-pc-linux-gnu, GTK+ Version 3.4.2) of 2012-08-25 on hamsa, modified by Debian
A possible workaround without the ruby electric mode found here:

It was fixed by replacing last-command-char to last-commant-event.
