[PyKDE] eric3 install problem

[walter]

hello,

I am trying to install eric3 on a ubuntu system

I have installed it with Synaptic, the built in ubuntu installer

I get the follwing error when I try to start eric 3

These errors come after I see the mascot splash screen

otyet at ubuntu:/usr/bin$ ./eric3
Traceback (most recent call last):
 File "/usr/lib/site-python/eric3/eric3.py", line 147, in ?
