Interesting.  2608166010582208512 in binary is 10010000110010000100010010101100000000000000000001000000000000.  Looks like the lower 32 bits are correct (being equal to 4096, which makes sense in this context), but the upper 32 bits are uninitialized or otherwise mangled.

I haven't upgraded to Lion yet, so I can't easily run this myself, but can you get a backtrace via gdb?  Just run gpg under gdb, and "break malloc_error_break", then "run --card-status".  It'll stop at the breakpoint, and you can then do "bt full".
