Intellij fails to launch after installing Eclipser

I've got the following exception:

Hi! Thank you for reporting the issue!

In order to identify the issue, please let me know the following:

• what version of IntelliJ are you using
• what version of Eclipser have you installed
• how was Eclipser installed
• what happens if you uninstall just Eclipser plugin

[stijnvanpoucke]

I'm using Intellij 15.2 on OS X 10.11.2 I've installed eclipser 0.7.1 via preferences > plugins > browse repositories Nothing changed by uninstalling eclipser from the plugins directory but I've fixed it by removing python from that directory and installing eclipser again...

Well, I suspected it was not Eclipser. As the error says "Unexpected node Pythonid".
