Closed Issue: Resize threw exception once [1401]

After calling resize I once (and only once) got this error
ImageMagick.MagickBlobErrorException: unable to write blob '(null)\magick_opencl_GeForce_GT_520_3d40ccf0_32.bin': No such file or directory @ error/blob.c/BlobToFile/266
at ImageMagick.NativeInstance.CheckException(IntPtr exception, IntPtr result)
at ImageMagick.MagickImage.NativeMagickImage.Resize(String geometry)
at ImageMagick.MagickImage.Resize(MagickGeometry geometry)

after that resize worked fine when called again (even on the same picture). Any ideas what could be the reason?
