[Python-modules-team] Bug#631554: ipython pylab file save fails with "couldn't create slave"

[Tom Kuiper]

Package: python-matplotlib
Version: 0.99.3-1

When I use the Save File button on the matplotlib toolbar and select EPS 
format I get this:

In [23]: run disp_search_sim.py

In [24]: (15525) KSycocaPrivate::openDatabase: Trying to open ksycoca 
from  "/home/kuiper/.kde/cache-kuiper/ksycoca4"
kfilemodule(15525): couldn't create slave: "Unable to create io-slave:
klauncher said: Unknown protocol ''.
"
kfilemodule(15525): couldn't create slave: "Unable to create io-slave:
klauncher said: Unknown protocol ''.
"
Some applications like LaTeX and Dolphin preview cannot read the 
resulting file.  Other applications like Imagemagick display and 
Gwenview can read the file and can save them as a bitmap EPS that LaTeX 
and Dolphin preview can read.
