Problems Mac 10.7.2 Installation pack EncFS encfs_askpass

Hi,

I already use EncFS successfully on one Mac reading data crypted on a Windows machine with Boxcryptor.

Now I tried to install the package on another Mac machine and I do get the following error message:

encfs_askpass(265,0x7fff78320960) malloc: reference count underflow for 0x40011cd60, break on auto_refcount_underflow_error to debug.

I am not a techi - can anybody help me?

Thanks in advance.

Chris
