Spyder freezes on assigning a fits table data

[elinor-lev]

Description

Apfter successfully importing a fits table with pyfits, Spyder freezes (100% CPU) when assiging the table data to a variable.
What steps will reproduce the problem?

1. open spyder
2. Run these lines:

from astropy.io import fits as pyfits
f = pyfits.open('morphtable.fits')
tbdata = f[1].data

What is the expected output? What do you see instead?
expect to have a new ndarray tbdata contain 500 lines and 300 columns and get prompt back after few seconds.
Instead do not get prompt back, CPU runs at 100% and memory allocation gets increased.
Even if it occasionally manages to assign it, Spyder runs very slowly afterwards (few seconds after just hit 'enter').

Please provide any additional information below
This works perfectly from a simple ipython console outside spyder.
This only happens in MAC OSX 10.10.5, it worked fine in another spyder installation on Linux.

A couple of questions:

1. Could you upload somewhere a fits file to test this use case in our side?
2. tbdata should be an ndarray or a subclass of it?

Also, could you try closing the variable explorer pane ?

Closing the variable explorer indeed solved the issue! Thanks!

I attach it here just in case.

@elinor-lev, It seems Github doesn't receive attachments. Could you upload it somewhere else?

Sure, you can find it here:
