+    Only install translation files from trusted sources.

+    Translation files are binary files that are generated from text-based
+    translation source files. The format of these binary files is strictly
+    defined by Qt and any manipulation of the data in the binary file may
+    crash the application when the file is loaded. Furthermore, even well-formed
+    translation files may contain misleading or malicious translations.
