Pressing backspace when a mode is active kills awesome.

[potamides]

Just to clarify, this bug is not caused by modalawesome, but by the Lua API of awesome. However since I was approached about this multiple times, I hope this issue will help users to find possible solutions and to solve confusion about this in the future.

This problem is already fixed in the development version of awesome, the related issue can be found here. I can think of two
things that can be done to fix this behavior:

1. You could install the git version of awesome.
2. You could apply the fixes yourself in your installed version. The problem can be fixed by changing two lines of lua code.
