+Subject: [PATCH] Fix misparsing of maketext strings.
+
+Case 61251: This commit fixes a misparse of maketext strings that could
+lead to arbitrary code execution.  Basically, maketext was compiling
+bracket notation into functions, but neglected to escape backslashes
+inside the content or die on fully-qualified method names when
+generating the code.  This change escapes all such backslashes and dies
+when a method name with a colon or apostrophe is specified.
