<div>Me and Pierre were discussing the same issue on IRC a few yesterdays i think.</div>
<div>According to Pierre it could be a issue with QWeakPointer's and we should use QScopedPointers.<br clear="all"></div>

<br></blockquote><div><br>Actually, I believe it was a very different issue, since the backtraces are totally different:<br><a href="http://paste.kde.org/~shadeslayer/2488/">http://paste.kde.org/~shadeslayer/2488/</a><br>
<br>And that's not quite the conclusion I drew of this conversation, but my attention was drawn towards the fact that we were using QWeakPointer without a QSharedPointer, which seemed weird at first.<br>In any case, for those who are curious, here's where the discussion led:<br>
