Subject: Don't accumulate arguments in `Entry.GetTranslation`
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=47a2bcf6e844292c7754cf9bd726a5416e5ad24a;p=libevent

Don't accumulate arguments in `Entry.GetTranslation`

Initialize `extradict` safely to avoid accumulating arguments in dict
objects passed in across calls.
