Comment 4 for bug 66725

The Problem is:

      <keyword-list _name="Command" style="Keyword" case-sensitive="TRUE"
                match-empty-string-at-beginning="FALSE"
                match-empty-string-at-end="FALSE"
                beginning-regex="\\">
                <keyword>\\</keyword>
                <keyword>begin</keyword>
                <keyword>end</keyword>
                <keyword>documentclass</keyword>
                <keyword>newcommand</keyword>
                <keyword>newenvironment</keyword>
                <keyword>newtheorem</keyword>
                <keyword>newfont</keyword>
                <keyword>part</keyword>
                <keyword>chapter</keyword>
                <keyword>section</keyword>
                <keyword>subsection</keyword>
                <keyword>subsubsection</keyword>
                <keyword>paragraph</keyword>
                <keyword>subparagraph</keyword>
                <keyword>page</keyword>
                <keyword>equation</keyword>
                <keyword>figure</keyword>
                <keyword>table</keyword>
                <keyword>footnote</keyword>
                <keyword>footnotemark</keyword>
                <keyword>footnotetext</keyword>
                <keyword>mpfootnote</keyword>
                <keyword>enumi</keyword>
                <keyword>enumii</keyword>
                <keyword>enumiii</keyword>
                <keyword>enumiv</keyword>
                <keyword>label</keyword>
                <keyword>pageref</keyword>
                <keyword>ref</keyword>
                <keyword>onecolumn</keyword>
                <keyword>twocolumn</keyword>
        </keyword-list>

        <pattern-item _name="Keyword" style="Others">
                <regex>\\[a-zA-Z]+</regex>
        </pattern-item>

Both are match the same string and gtksourceview don't know what to do. The keyword-list needs a higher priority or the pattern-item shouldn't match the same string.
Any Idea?
