Hello all,

I am facing an issue with the packages rqt_graph and rqt_tf_tree. When I run the mentioned packages I get the following error:

PluginHandlerDirect._restore_settings() plugin "rqt_graph/RosGraph#0" raised an exception:
Traceback (most recent call last):
  File "/opt/ros/indigo/lib/python2.7/dist-packages/qt_gui/", line 116, in _restore_settings

    graph.nodes_iter = graph.get_node_list
AttributeError: 'list' object has no attribute 'get_node_list'

Any clue on how can I fix this problem?

Does this persist if you remove .config/ (make a backup first)? It might be in a slightly different location, depending on your desktop environment.

Yes, the problem persists after the remotion of the mentioned file.

Must say I have no idea, have not run into this myself. Something like this seems similar. Do you have any name in your ROS tf tree that contains a character that pyDot might not like?

No. I am just running roscore and the command rqt_graph.

Got the same problem, ROS indigo on OSX. Originally I had the error NameError: global name 'dot_parser' is not defined , then I updated pydot and pyparsing from 1.0.2->1.2.2 and 2.1.4->2.1.5 and got your error.

So I found some versions that seems to work (ROS indigo, /rosversion: 1.11.20, OSX).

I downgraded pydot to version 1.0.29: pip install pydot==1.0.29, and now rqt_graph seems to work fine.

Could you report this at ros-visualization/rqt_common_plugins/issues? Thanks.

Thanks! Downgrading pip worked for me. Was facing the same issue with ROS Indigo on Mac OS X El Capitan

Downgrading works for Jade too. Thanks!
