Truncated data on some blocks

[coinwarp]

After parsing some blocks some CScripts seem to contain truncated data erros like <ERROR: PUSHDATA2: truncated data>

eg printing block 884490

CAltcoinBlock(6422786, lx(8bb6225bda07ff9bfc65c563678d2558a25f7b3bc4edbf14ae720eb48dc0d540), lx(1b1d5cb0406dff3110e9154990475ed193d939d4bb85226999c1b9128ec731b0), 1442788081, 0x1b04dc69, 0x00000000, CAuxPow((CTxIn(COutPoint(), CScript([x('450c0d'), x('f232ff55'), x('034271e85b0d0900'), OP_SMALLINTEGER, CScriptOp(0xbe), OP_2DROP, OP_2DROP, CScriptOp(0xf7), CScriptOp(0xe7), x('43ccff490afaa4695ae8a0eab15ecd8ff02af7d9a0fb07a424961a40000000000000000d2f6e6f64655374726174756d2f')...<ERROR: PUSHDATA2: truncated data>]), 0x0),),

I've added a test case to cover specifically this, but without a lot of luck recreating it so far. Could you modify https://github.com/rnicoll/python-altcoinlib/blob/master/altcoin/tests/test_core.py#L57 to generate the error, please?
