[Qt-interest] Analyze memory errors

[Diego Iastrubni]

Just a "me too":
I found leaks in QPlainTextEdit as well. A lot inside oxygen  (kde style
plugin). I assume that or Qt5.1 this will bea higher issue? I understand
that 5.0 will not have a "valgrind clean" goal, but 5.1...?

Just a long shot: 4.8 ....?
