Do you see substantial growth in memory usage? Then massif can give us a hint.

My first suspect was pixmap generation and the progress dialog, but I think
this problem was fixed already. To rule out a problem here, disable the
relevant lines 183 and 184.

There is only a QStringList in the fingerprints generator, I doubt that is the
problem.

Second step is the HaarIface. To rule out any problems here, you could try to
use a fresh HaarIface object any time.

If all does not help - though it takes longer - we'd need to run digikam under
callgrind, and switch on instrumentation as soon the presumed bug's calculation
time is significant, like > 50%.
