When two instances of smelter share the same CEF
root_cache_path
, one instance becomes the main browser window, and the other acts as an opened "tab" in that browser. We don't handle that case at all, hence the crash. Fixed it by giving each instance a uniqueroot_cache_path
so now each instance works independently.Fixes: #1014
