5406zl - core pair stops working, when configuring empty spaces in VLAN Names

[rquack]

I have a pair of 5406zl  running firmware 15.05.0006. I know there is a newer Version availiable 15.06.0008, but I can't update so quickly.

we run about 20 distributed trunks on CU Modules.

I have a reproducable error, and maybe someone could confirm it in a test-environment :

1. configure a vlan3, called "Server"

2. configure a vlan4, called "Server PROD"       ( With entering this both switches stop working, console is lost. console to second core is lost too : Big network outage ;-((

You can recover from this error , by cold booting the 1st  configured core.  

There is no problem in step2 using "Server_PROD" , it is always a crash when using an already existing VLAN Name +  followed by an empty character.

Should have known not to use spaces since the old DOS days , but VLAN names are exspected to be simple strings, right?

Thank you
