Segfault in read_table
Hello,

I get a segfault in pandas version `0.10.0.dev` when attempting to import a tab-delimited file with `pandas.read_table`.

Here is the code that produces the bug:

``` python
# note:  tf is a string containing the path to the file
pd.read_table(tf, names=range(1, 129) + ['ref'], header=None)
```

I tried loading the data into a list and then passing it to the `DataFrame` constructor and was successful.  Here's what I did:

``` python
with open(filename, 'rt') as f:
    # there is only one line because this file was encoded using '\r' instead of '\n'
    data = f.readlines()[0] 

# remove the empty strings that occasionally pop up
data = [[s for s in line.split('\t') if s] for line in data.split('\r') if line] 

pd.DataFrame(data, columns=range(1, 129) + ['ref'])  # works
```

[Here](https://dl.dropbox.com/u/6160029/data.txt) is some example data that you may use.
