Workaround
The workaround should only be used at your own risk and should be first tested on a test environment. When performing in production make sure to create a full offline database backup first

1. Shut down FishEye/Crucible
2. Create a full database backup
3. Locate the path with the space in its name in the cru_content_root table and delete the row
4. Start FishEye/Crucible
