Bug #88835
Updated by Peter Niederlag almost 5 years ago
According to documentation one can set Install Tool configuration "[HTTP][proxy]" to an array to be able to set different proxies for http/https or to set the no_proxy option.
When we set this configuration via an editor the Settings Module "Configure Installation-Wide Options" will die with an Exception. :-<

On this spot item.value will be an array, resulting in the exception as arrays can't be cropped
