Matplotlib does not work with Canopy 1.3 on Linux Mint Debian Edition

Question

I recently upgraded to Canopy 1.3 on my Linux computer, and since then I am experiencing problems when trying to use Matplotlib. I did not have these problems with Canopy 1.1.

Invoking Matplotlib will always spawn an error like this:

>>> import matplotlib.pyplot as plt
>>> import numpy as np
>>> plt.plot(np.array([1,2,3]))


*** libmkl_p4m.so *** failed with error : /home/richard/Canopy/appdata/canopy-1.3.0.1715.rh5-x86/lib/libmkl_p4m.so: undefined symbol: i_free
*** libmkl_def.so *** failed with error : /home/richard/Canopy/appdata/canopy-1.3.0.1715.rh5-x86/lib/libmkl_def.so: undefined symbol: i_free
MKL FATAL ERROR: Cannot load neither libmkl_p4m.so nor libmkl_def.so

Apart from that, Canopy Python seems to be functioning normally.

This is on Linux Mint Debian Edition (LMDE) i386, a distribution that is based on Debian testing.

$ uname -a
Linux lmde-i386 3.11-2-486 #1 Debian 3.11.8-1 (2013-11-13) i686 GNU/Linux

I have already searched the Canopy/EPD support forums, but to no avail. (This issue at first sight seemed to be related; but the proposed fixed does not help.) All I could find was a posting in an Intel support channel, which indicates the problem might be due to incorrect linking.

Any hints would be greatly appreciated!

Reinstalling (~/Canopy) is very unlikely to help. But resetting your user environment might. Delete ~/Enthought, then restart the Canopy application to rebuild your user environment, then try again. If that fails, please email support@enthought.com with a reference to this SO question.
