Package: jupyterlab
Version: 4.4.10+ds1+~3.1.0+~0.16.6+~cs1.4.4-4
Severity: important
X-Debbugs-Cc: [email protected]
I have problems with the jupyter lab client. Obviously it is running into an
endless loop.
After starting the server with `jupyter lab` in my notebook directory, the web
browser comes up and loads jupyter lab. The logo animation works but
afterwards, the window hangs showing the logo. When I click into the window
Firefox complains about the website slowing down my computer.
In the javascript console I found the following:
