SSH Botan library exception on Mac

Hi,
I got the following error msg when trying to establish an ssh connection to a device:
"Connection failed: Botan library exception: PK_Verifier: No working engine for RSA"

I had this issue in the two cases:

• When trying to debug an application on a BB10 device ( the BB10 plugin fails to connect to the device via ssh)

• When Configuring a Meego/Harmattan device. On the "key Deployment" step, the ssh connection fails.
