Anyone knows what this is all about?

I too have been seeing occasional segfaults in PI, mostly when it needs to refresh the image histograms after I have performed some operation on an image. Just had one this morning, but PI seems to have recovered. I should probably have quit and restarted PI, but I haven't noticed anything awry by not doing a clean start.

In the one from this morning, it looked like it was trying to free up all temporary cache space. It seems to be an interaction between the histogram module and Qt.
