-- Information about the crash:
Kdevelop crashes -- there is no pattern of when it crashes.  Sometimes while I'm typing; other times when I'm pasting something.  The only commonality that I can see is that it crashes when there are at least two sessions open (with different Session names and projects).  The crash  does not happen immediately; sometimes after a couple of minutes...other times longer.

When I have only one session open, it [seems to] never crash like this.



The crash can be reproduced some of the time.
