#1561 AttributeErrors upon pydevd.settrace

[Josh Davidson]

The first time I attempt to settrace with pydevd there are bunch of AttributeError exceptions. If I invoke settrace a second time, the connection is successful

>>> import pydevd                                                                                                                                                                                
>>> pydevd.settrace()

Hi there, this tracker is disabled for now. I've started a funding (http://igg.me/at/liclipse) to keep supporting PyDev and if the funding works, I'll create a tracker where you should post issues like this (so, please buffer this request and add it to the new tracker when the funding goes through).
