bitbake dies with an python exception | AttributeError: 'NoneType' object has no attribute 'rfind'

[Cestonaro Thilo <thilo.cestonaro@ts.fujitsu.com>]

hey,

can someone point me in the right direction what actually goes wrong?

Looks very strange, so no recipe or compile error but rather than a bug 
in bitbake.

Greetings
Thilo
