Completion hangs with Python 3.4.3

[timtroendle]

When I recently upgraded to Python 3.4.3 SublimePythonIDE stopped working properly and always hangs while typing. This issue does not exist with Python 3.4.2, I can reproduce that.

I'm on a Windows machine and I installed Python through conda.

The console shows recurring server starts roughly every 1-2 seconds with Python 3.4.3 as soon as I start typing:

 started server on port 52372 with C:\Miniconda3\envs\default\python.exe
 started server on port 52374 with C:\Miniconda3\envs\default\python.exe
 started server on port 52376 with C:\Miniconda3\envs\default\python.exe
 ...

Any idea what's happening here?
