Comment # 2 on bug 1036928 from Johannes Weberhofer

Thanks for notifying! There is a update available at
https://github.com/fail2ban/fail2ban/commit/607568f5da9e6b962c43d59280d72bd678c08afa
; I'll see to include it into the current version. 
@miuku it would be great if you could verify upstream's new filter works for
you.
