What I was doing when the application crashed:
I was doing some operations on one file, then I went back with undo and then
wanted to redo the operations again, I hit the redo button several times pretty
fast and it crashed

What I was doing when the application crashed:
when I was trying to redo an operation in umbrello, it crashed ;)
I was doing some moving of classes and connecting classes with arrows before,
then wanted to undo a connection which didn't work, so I redid it and it
crashed

Comment 7 Dario Andres 2011-01-31 01:09:28 UTC 
From bug 237583:
-- Information about the crash:
What happened: I was working with a relatively simple class diagram, involving
2 boxes, 2 labels, about 14 classes, and about 6 packages.  Having accidentally
deleted a box rather than an association, I pressed undo.  Nothing happened in
the diagram.  I noticed the undo history seemed to be changing in the middle of
the history, rather than at the bottom or top.  Pressed undo a few more times,
no diagram change for about 6 goes, then stuff I did much earlier began to
disappear as I kept pressing undo.  Switched to redo, and it crashed
immediately on the first redo.

It may or may not be related, but prior to this, I had noticed that clicking
the dependency toolbar button had no effect for a few clicks (button seemed
non-responsive), then suddenly worked with no actions taken to fix it. 
Computer was not lagging.

New crash information added by DrKonqi

umbrello (2.6.2) on KDE Platform 4.6.2 (4.6.2) using Qt 4.7.2

- What I was doing when the application crashed:

I was trying to undo and redo my previous changes. Though undoing the actions did not make any real change to the diagram. Even after undoing 5-7 steps, the diagram remained the same.
