Yupp the d3dx9d_33 specifies the debug dll instead of the retail one which would be what you first pointed out. Missed the d there and therefor only answered to the version part.
That error definitely needs to be fixed as it means crash on most systems and kills the performance. (above that it can affect shaders and lead to anomalies)
