If somebody would like to do it please go ahead.
Unfortunately I have absolutely no time to work on IDE anymore as I have moved on other projects so unless the issue have no known solution/workaround (this one has such) I'm rather reluctant to pick it up as there is a plenty of more higher-prio kernel wide issues (including things like mm regressions) to fix.

or more likely:
3) the issue is highly configuration dependent and not worth the hassle given the known solution/workaround

BTW Please always Cc: David first on all IDE issues as he is the main IDE slave now and the transition period is long over.
