Agent Problem

I am using matplotlib since three months, every thing was fine untill today I have got this error message which is strange and I could not figure out what it means.
here I paste the error message I got.

“”"
Another agent is running…
Failed to allocate the agent. Exitting…
Failed to invoking the agent: No such file or directory
Cannot launch the agent
The messenger is now down

“”"

Does somebody knows where it comes from and how to cure it?
Thanks in advance

This looks like a KDE/Qt problem, not a matplotlib problem, eg
googling for the phrase,

   Failed to invoking the agent: No such file or directory

turns up hits like this:
