[matplotlib-devel] BUG: Qt4Agg backend save figure io-slave error

[Philippe M. <phi...@ce...>]

Dear all,

When I use the Qt4Agg backend and I want to save the figure by clicking the 
save button, I get this Error message:

kfilemodule(5951): couldn't create slave: "Unable to create io-slave:
klauncher said: Protocole «  » inconnu.

It is like an empty string is given for the protocole name.

infos:
Distribution: Archlinux
Python 2.7.3
matplotlib 1.1.1
Kde 4.8.4
Linux  3.4.5-1-ARCH x86_64

Best regards,
