Exception "Sorry but parent: Project (Disposed) ... has already been disposed"

[uwolfer]

Exception message: Sorry but parent: Project (Disposed) project_name has already been disposed (see the cause for stacktrace) so the child: null 24506114: running=false; canceled=false; task=null will never be disposed

Addition information:
I had a project open. I opened an additional project window to look at its file watcher settings. After using the windows snipping tool to copy the file watcher settings I closed the additional project window. I made the desired changes to the filewatcher and added and removed empty lines to an .scss file to see whether the changes had the desired effect.

I committed the changes already made to the original project through the version control window. I then opened the gerrit window to see whether I had already merged changes made previously that day. At this point the error occured for the already closed additional project in the project I was originally working on.
