Antimagic broken in SCS?

I'm running into some bugs in my SCS install (see also this Gibberlings 3 bug report). The bug is as follows (and occurs on both my macbook pro, and my separate Windows install -- the only slightly sketchy thing I might be doing is that I used the SCS hotfix instead of BW fixpack).

1. One member of my party (also works for Spellhold Irenicus and an Elder Orb in the Underdark) casts spell deflection (or minor spell deflection, spell turning or spell trap).
2. Another member of my party casts secret word (or similar) at the first member.

The bug is that the spell deflection is not removed, there are not console messages about "Spell protections dispelled." and a followup breach fails (Note that I know about the limitations of secret word vs spell trap). Do you guys get this bug too? Can anyone repro it? Is there a reasonable workaround?
