Description of problem:

python3-matplotlib has a missing dependency (that I was unable to find) causing a crash in tk backend when show() is called. 

 
Version-Release number of selected component (if applicable):
python3-matplotlib-1.2.0-8.fc18.x86_64


How reproducible:

always

Steps to Reproduce:
$ python3
> from pylab import *
> plot([0,10])
> show()


Actual results:

Exception in Tkinter callback
last line is "TypeError: can't use a string pattern on a bytes-like object"
looks like font related (?)
figure window shows but its empty.


Expected results:
show plot
