Created attachment 114298 [details] Video of the leak I've noticed that when I run some math krunner has a memory leak that increases a lot the ram and cpu used, sometimes I have to kill it because it reaches 500-700mb after a while and the whole system becomes slower. I thought that it was because of "unmatched" parenthesis, but the problem seems to happen also when they match. I have all plugins enabled a part from the spell checker one. Check the video for an example (krunner was killed and just started, with nothing else running on the system)
I tried this out and it is still leaking, but not as extreme and not directly related to the calculator runner. *** This bug has been marked as a duplicate of bug 386513 ***
