Hmm, seems like it was related. I fixed some issues with my installed packages, removed the files I was trying to fix in my previous post and installed the package libssh2-1:

Terminal

xbian@xbian ~ $ sudo rm /usr/lib/arm-linux-gnueabihf/libssh2.so.1
xbian@xbian ~ $ sudo rm /usr/lib/arm-linux-gnueabihf/libssh2.so.1

xbian@xbian ~ $ sudo apt-get install libssh2-1

This fixes the libssh2 files, and also lowers the cpu usage of xbian back to normal levels. Not sure how libssh2 got corrupted... And why it has such an impact on cpu usage.
