Entering command-line window while loading workspace results in an error

[opalmay]

Steps to reproduce:

1. Open a workspace file (So it shows the "Loading workspace" indication)
2. Press q: to go inside the command-line window while the workspace is still loading
3. The following error will appear once or more:

The "Loading workspace" indicator is then permanently stuck.
