New crash information added by DrKonqi

akregator (1.6.6) on KDE Platform 4.8.4 (4.8.4) using Qt 4.8.2

- What I was doing when the application crashed:

I had just done a full refresh, which seemed to have finished.  In the tree
pane on the left I had a closed folder of feeds that I'm not interested in at
the moment, so I right-clicked on the folder and pressed "mark feed read". 
Akregator immediately crashed.

When I've had this problem before over the last 3 years it's been blamed on
corrupt files imported from KDE3 but I don't believe this is correct:

1, last time I imported from KDE3 I spent some time checking the metakit
archives out with metakit tools, and no problems were apparent

2. this only ever happened once for each feed, and almost never happened first
time into the feed but only at some random time later.  so it's not a
corruption of the feed itself as that would cause akregator to crash every
time, but something about the feed that catches akregator on the hop when it is
doing some other task at the same time

2. this hasn't happened since then in eight months of daily use of KDE4
akregator, but is apparently still an occasional issue.



The crash is not reproducible at will but will occur sooner or later.
