Veyon master crash with "show current location only" (LDAP Pro Add-on)

[Gaelds]

hello,
I can't use LDAP pro Add-on on our teacher/students computers because it crashes everytime I enable "show current location only" option in "Behaviour" tab. On my admin computer where "show current location only" is disabled, the same configuration works fine. I tried with latest veyon 4.9.0
