When using Chrome on a Mac I am able to expand navigation items in the tree, but as soon as you try to collapse anything on the tree the page crashes with the Chrome "Aw Snap! Something went wrong while trying to display the webpage." I also see the same issue when viewing the demo sites on SourceForge for versions 4.0.6 and 4.1.0. I also verified that this happens on both the original theme and the pmahomme theme.
This issue does not happen in Safari or in chrome running under windows on the same computer.
I'm also not getting any errors or warnings in the chrome console or any chrome crash reports, so I haven't been able to determine which part of the code is causing the crash.
