How did you install those plugins?

[jcalbert]

The general context is an old and ugly anaconda environment. At some point in antiquity:

conda install line_profiler
conda install memory_profiler

More recently: conda install spyder led to repeated crash-on-launch.

Then

conda upgrade qtpy
conda upgrade pyqt

got Spyder booting again, and it raised window asking to submit the above bug report. I haven't tried using those two plugins since updating spyder to 3.2.

Please remove this file

spyder_line_profiler-0.1.1-py2.7.egg-info

That should fix this error.
