Valgrind tells us 'count' is uninitialized (see line 83).</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">This patch
- moves variables to local scopes
- initializes the variable count with 5 times 0.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">The backtrace in bug https://bugs.kde.org/show_bug.cgi?id=357341 is fixed this way. However, there is a second crash still happening, which still needs investigation.</p></pre>
