[Qt-creator] possible leak in 2.5 rc with parsing after cmake? - traced to todo plugin.

On a hunch I disabled the todo plug-in (in the src/plugins/plugins.pro file), and found qtcreator doesn't show signs of a memory leak anymore. This meets my current needs, though the plugin sounds handy (I think there are hundreds of todo comments in our codebase that nobody is looking at)
I tried running in valgrind, but on my 32-bit system and project there isn't enough memory to do more than start and exit qt creator before valgrind runs out of memory. (I thought I found a work around, but the power went off, and given the speed of valgrind I don't want to try again).

Just running Creator under valgrind might give some insight.
