Hi Alex,  
I was not able to reproduce this with the MNE sample data. Please find the  
data files (stc and src) from my study that caused the problem here (  
[https://www.dropbox.com/sh/qddmd9vr8rg7hw8/00drNDyuqW](https://www.dropbox.com/sh/qddmd9vr8rg7hw8/00drNDyuqW)). Thanks in advance.

Kam

Hey Kam,

It looks like your `stc` somehow has (many) vertices that are not in the  
source space. It also looks like that STC has 10242 vertices per  
hemisphere, consistent with an ico-5 source space, while the `src` you sent  
has 4098 vertices per hemisphere, consistent with an oct-6 source space.  
Did you perhaps morph the data to fsaverage ico-5?

I'm opening a PR for mne-python to catch this and throw a better error.
