Broken: 2.75a c27589e
**Short description of error**
Pressing AltGr forcing Blender generate double event on keyboard press
**Exact steps for others to reproduce the error**
1. Press AltGr + I for example, then Esc
2. Every simple key-press becomes double, even in textfields (ddoouubbllee..bblleenndd)
Maybe this bug caused by some crappy keyboard drivers from my notebook vendor.
