Comment 1 Alex Merry 2010-09-03 20:51:47 UTC 
OK, so it happened again.  This time, what I did was (and this is very similar to what I did the previous time):

The posts were filtered from the previous instance of Akregator.  I pressed "-", which took me to a feed that had no results for the filter (although one unread post).  I cancelled the filter, and typed "-" to attempt to read the unread post.  This typed the character into the filter, so I immediately backspaced it.  At this point, Akregator crashed.
Comment 2 Alex Merry 2010-09-03 20:54:53 UTC 
Tested once more: the crash can be triggered by typing in an character to the filter field (when it is empty), but only for one of the feeds.  The other feeds (both with and without unread posts) don't crash when I do this.
Comment 3 Christophe Marin 2010-09-14 22:30:55 UTC 
Please retry with a more recent snapshot, a recent commit was reverted in trunk
Comment 4 Alex Merry 2012-06-11 16:05:59 UTC 
This hasn't happened to me since, so I'm resolving as WORKSFORME.
