I would suggest using the "Unlimited" history mode in that case, it uses a file instead of storing everything in memory.

I wasn't able to detect anything amiss with Valgrind. ( valgrind --leak-check=full konsole ) 

The memory usage does appear to increase when the "Clear All Histories" is invoked for the first time, but subsequent fill-history -> clear-history -> fill-history cycles don't increase the usage any more. 

If you do repeated fill-history -> clear-history -> fill-history cycles, does the memory usage continue to increase significantly?
