      glyph_metrics_t QTextEngine::boundingBox(int from, int len) const crashes when using Thai language Vista and Thai string are added to a combo-box.
      The crash occurs on the line:

      glyph_t glyph = glyphs.glyphs[logClusters[pos + ilen - 1]];

      due to logClusters[pos + ilen - 1] exceeding the array bounda of glyphs.

      The attached example code demonstrates this.
