Description Alex W 2006-01-10 18:23:59 UTC

Version:           1.5 (using KDE 3.5.0, Gentoo)
Compiler:          gcc version 3.4.5 (Gentoo 3.4.5, ssp-3.4.5-1.0, pie-8.7.9)
OS:                Linux (i686) release 2.6.14-gentoo-r5

Undo clicked twice
Umbrello, so nice,
gone.

To reproduce:
In the sequence diagram (and other places) make a few changes. Click undo twice.
Umbrello crashes.

Expected behaviour:
A second level of undo.

Comment 1 Ian Vaughan 2006-02-11 00:00:15 UTC

On testing this I managed two undos ok, but then the first redo crashed it!
On general usage sometimes two undos crashes it for me as well.

This only seems to occur after some "heavy" usage, ie if on clean open just create a load of objects, they can all be undone ok.

Tested with v1.5
On Linux (i686) release 2.6.12-12-386
Compiler : Target : i486-linux-gnu
(From Ubuntu apt)

Comment 2 Oliver Kellogg 2007-06-19 22:48:03 UTC

Hmm... Does this still happen with a more recent version (e.g. 1.5.71) ?

Comment 3 Oliver Putz 2007-12-10 20:53:48 UTC

Yes, this still happens with a more recent version. I can reproduce this in the current (746734) kde4daily svn build.

Smalletst testcase to reproduce:

1) Create new Sequence Diagram
2) Add one object to sequence diagram
3) Add asyncronous message from object to itself
4) Undo (this erases the asyncronous message as well as the object!)
5) Undo again (this crashes umbrello)

So at least here, there is no need for heavy workload before doing the undos...

Funny thing: Umbrello 1.5.7 in my KDE 3.5.7 (Gentoo) does not crash.

Comment 4 Oliver Putz 2007-12-17 06:10:51 UTC

A little edit to my last edit where I said this would not happen in umbrello 1.5.7 under KDE 3.5.7. The bug is visible there too. Just that I need to make three connections between the two classes in the sequence view and need to click undo real fast (like "triple-clicking" on the undo button)

Below are a simple and a full backtrace for this bug in umbrello 1.5.7 under kde 3.5.7 in Gentoo.

Comment 6 FiNeX 2009-08-05 22:15:14 UTC

Reproduced the crash using current trunk (r1007390)

I've followed the steps from comment #3 and it crashed with the following backtrace:


Application: Modellatore UML Umbrello (umbrello), signal: Segmentation fault
[KCrash Handler]
#5  UMLWidget::setLineColorcmd (this=<value optimized out>, colour=<value optimized out>) at /usr/include/Qt3Support/q3canvas.h:164
#6  0x0000000000000000 in ?? ()



It looks like it still using something from Qt3...
