How to reproduce
-----
1. Created a plot using matplotlib plot(), show()
2. Hit 'save' button on the plot
3. A dialog starts to appear,
4. Close the broken dialog

I also got this:
python read_data.py
(9217) KSycocaPrivate::openDatabase: Trying to open ksycoca from  "/var/tmp/kdecache-nbecker/ksycoca4"
kfilemodule(9217): couldn't create slave: "Unable to create io-slave:
klauncher said: Unknown protocol ''.
" 
kfilemodule(9217): couldn't create slave: "Unable to create io-slave:

" 
Segmentation fault (core dumped)

Thank you for reporting this bug.

How reproducible is this problem?

What is the output of running the following command?
  rpm -qa hplip "qt*" PyQt4 numpy python-matplotlib

Looking at the backtrace, it looks like the problem occurred in the program's single thread in QMultiInputContext::~QMultiInputContext

Reassigning component from "python" to "hplip";  hopefully the hplip maintainer will be able to figure this out further or reassign as necessary.

(Alternatively, it _might_ relate to recent numpy/python-matplotlib ABI issues, though IIRC that was just on F13 and F14)
