Description

Smuxi crashes directly on startup with this exception:

Added by Mirco Bauer 5237 days ago

Added check to only use default(T) for value types, fixing the startup crash. (closes: #405)

The config backend returned null values for empty strings when using the
Get<T>() method which GetList() does. That happened because value types like
bool and int need extra handling in case the value is empty using the
default(T) construct. This extra handling was also applied for regular string
values and default(string) returned null.
