"minergate crashed with SIGILL in blake256_compress()". Something to do with the libmonerominerplugin.so.
Running it from the terminal gives "Segmentation Fault (core dumped)"
The crash happens as soon as any of the coins (don't know about LiteCoin) start mining on any number of cores.

This is on a fresh install of Ubuntu 13.10, with an AMD Phenom II X4 910e. This also happens on Ubuntu 14 when bypassing the dependency issues this has. Running the simpleminer and bytecoin works fine. I have the crash report files if anyone wants it.
