I've been trying to make my own rqt plugin. After a lot of back and forth, I finally got it to build. The problem now is that rqt won't run. I get the message listed below. In the last line, rqt_mypkg is listed as KeyError. This is a package I had once before, but is deleted from my workspace now. I've tried cleaning and deleting my workspace, removing and reinstalling rqt, removing and reinstalling ros but nothing works. Rqt still won't run. Anyone have any idea what is wrong?

 Traceback (most recent call last):
  File "/opt/ros/kinetic/lib/python2.7/dist-packages/qt_gui/plugin_manager.py", line 454, in restore_settings

The package you removed is probably still referenced in an ini file that stores the settings for rqt (rqt tries to recreate your perspective from when you last exited the program; it can't find the plugin, hence the error).

You should be able to fix this by either removing ~/.config/ros.org/rqt_gui.ini, or by editing it such that the plugin is no longer referenced.
