crash of go program with no dictionary installed

[brettowe]

was getting a crash as listed below trying to use this and i traced it down to fact there was no dictionary installed the code around where it crashed should be speller, err = aspell.NewSpeller(map[string]string{ "lang": "en_US", }) if err != nil { fmt.Errorf("Error: %s", err.Error()) *fakeWords = false } defer speller.Delete()

so even with the error check its doing the below
