Profile picture is gone when editing the profile

If i change the email on my profile and set the checkmark to keep my profile image and press submit, then the profile image is gone and Lansuite writes "Bitte fülle dieses Pflichtfeld aus." on the upload profile image button.

What I've tried:

• Created new unprivileged user without profile picture - OK
• Uploaded profile picture - OK
• Changed Email address with existing profile picture - OK
• Removed Profile picture by deselecting checkbox - OK
• Changed Email address again without profile picture - OK
• Edited email of superadmin account without picture- OK
• Added profile picture to superadmin account - OK
• Edited email of superadmin account with picture - ERROR

Huh...
