python nodes freeze knime


I frequently used python snippets and python plots in knime version 2.6.3 (on scientific linux).

Now, after upgrading to knime version 2.7.3, knime freezes if a try to use one of these nodes.

As soon as I double-click on a python snippet node to configure it, knime doesn't respond to anything anymore and all I can do is to shut it down the hard way. Does anyone have an idea about that?


Thanks a lot,


Btw.: It is independent of the python version I use.


Hi Daniel, 

What operating system are you using?  




Hi Aaron,

I'm using Scientific Linux 6.3, but it was the same in 5.3. So it doesn't seem to be Linux issue.
