guest additions fails to start with special usernames

[saber002]

Host System: Windows 10 64bit Guest System: Windows 7 64bit Virtual Box Version: 5.1.6 Guest additions: installed

When I log into the guest system with a username "test", guest additions are working. When I log into the guest system with a username "test ö", guest additions are not working.

The problem is not the space character, it works with "test a". It is the german umlaut. If this character is part of the username (not the full name), then the additions won't start and furthermore all the functions like seamless integration and so on are not working.

Could you install the most recent 5.1 Guest Additions from our test builds page (Guest Additions >= revision 111520)? Please check if this build fixes your problem. Thank you!

I can confirm that GA builds >= rev. 11520 address the issue. Guests tested: WinXP, Win7-32, Win10-64.

Tried it with rev. 11520 and problem is fixed.

Thank you very much!
