Solution for wxGTK bug that causes backspace key NOT to work.

[stahta01]

The cause is having Linux Package "ibus" installed without having "ibus-gtk3" installed.

Solution install package "ibus-gtk3" (I also installed package "ibus-gtk"; not sure if needed.)
I needed to reboot the computer before the problem went away.

Found solution here https://bugs.launchpad.net/ubuntu/+source/gnucash/+bug/1306500
except they only said to install "ibus-gtk".

Problem happened on Linux Debian "Jessie" for me. Using Code::Blocks linked to wxGTK3.
