It appears pymvpa2-prep-afni-surf tries to run 3dSurf2Vol with a non-existant option, “-surf” instead of “-surf_1D”, but correcting this apparent bug results in another error: 3dSurf2Vol rejects __tt.1D with a “bad surf data file” error.

Indeed, going through the AFNI source shows that on 9 Feb 2012 an option "sdata" was added to src/SUMA/SUMA_3dSurf2Vol.c at line 2178 [1]. Maybe your AFNI version is from before that date?
Which version of AFNI are you using? Can you upgrade to the latest version and see if that fixes the issue?
