Our qt build shouldn't hit that crasher. do you see it?

kmail hung on deleting emails (although I could still view emails in other inboxes, just no tthe one in which the deleted emails were) and when I closed the program there as a crash popup notification.

Good news is that 4.8rc1 was *supposed* to drop the MALLOC_CHECK_ stuff from /usr/bin/startkde, but didn't. AND.... doing so makes this hard-crash go away (even though free'ing invalid pointers is still bad of course). kdebase-workspace-4.7.95-2 building, and on the way to repos soon.

I have just found another report + fix possibly related to #289693 https://bugs.kde.org/show_bug.cgi?id=289831

OK, I'll keep an eye on kde.bugs, maybe a comment and new back trace could be added to #289831 (which is marked as fixed) saying that the crash still happens.

Today for me too, Kmail2 crashed as described above. The crash happened after I had removed some email messages. Kmail2 got really lost. Header info and message bodies were mixed up, sometimes kmail2 hung up or crashed. So I think the problem - as Kevin already said - is not in the destroy methode (c.q. qDeleteAll), but is somewhere in the manipulating (creation/removing) methodes of the qList.

The next commit [2] reverts commit 1, but isn't in 4.7.95-1(2). Allen Winter says about these commits: "Revert "Add a bunch of validity checks to avoid crashes." This reverts commit baa76292fbbe4918a630203269e0822905db3503. I think I might have broken some things with this commit so I'm reverting it so I can test further."
