ProblemType: Bug
Architecture: i386
Date: Tue Jan 19 02:06:04 2010
DistroRelease: Ubuntu 9.10
ExecutablePath: /usr/bin/umbrello
InstallationMedia: Kubuntu 9.10 "Karmic Koala" - Release i386 (20091028.5)

Application that crashed: umbrello
Version of the application: 2.3.2
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-14-generic i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
Created an ER diagram with three entities. Populated entities with elements. When adding a foreign key constraint to an entity, umbrello crashes when pressing apply or save. Always happens. I have tried restarting kubuntu and closing all other applications, but I get the same problem.

- If you can reproduce the crash at will (or you experience this regularly), can you install the "kdesdk-dbg" package and post a complete backtrace here? Thanks

Thank you

also try to copy then paste the sessions entity ==> crash

Hi there!

Thanks for reporting this bug! Your bug seems to be a problem with the KDE program itself, and not with our KDE packages. While we appreciate your issue, it would be better if it was tracked at https://bugs.kde.org, so that the KDE developers can deal with this speedily and have direct communication with you as the reporter for more effective debugging.

Thanks!

model that crashes umbrello

I also have this problem with umbrello 2.3.4

try to add a foreign key constraint to "evenements" entity on the "sessions" entity ==> crash

also try to copy then paste the "sessions" entity ==> crash

One can see that UMLObject::getDoc get's an invalid pointer - 0x20 seems not to be in the regular data section

In Thread 1 (Thread 27796):
 #0 QString (this=0x20) at /usr/include/qt4/QtCore/qstring.h:711
 No locals.
 #1 UMLObject::getDoc (this=0x20)
     at ../../../umbrello/umbrello/umlobject.cpp:408

at this level listItem ist set to 0x20 - seems not to be valid too

 #2 0x080a4ac5 in ClassifierListPage::slotActivateItem (this=0x9843520,
     item=0x98f8aa0)
     at ../../../umbrello/umbrello/dialogs/classifierlistpage.cpp:350
         listItem = 0x20

and some levels above there is an invalid QEvent pointer (=0x20)

#62 0x011bf3ee in QAbstractButton::event (this=0x979a320, e=0x20)
     at widgets/qabstractbutton.cpp:1077

In the next level one can see that there is a QPushButton with an invalid d pointer (=0x20)

 #63 0x0126966d in QPushButton::event (this=0x979a320, e=0xbfcf7890)
     at widgets/qpushbutton.cpp:662
         d = 0x20

I get the exact same problem. It's 100% reproducible. I tried the same action sequence on the same file with Umbrello 2.3.4 and with 2.3.2 and both crashed exactly the same way.

Description of the actions taken :
- Create 2 entities : variable and unit
- Add a "id" attribute of type "SERIAL" to both entities and set it as the Primary Key
- Add a attribute named "unit" to variable
- Create a Foreign Key Constraint on referencing the id attribute of the unit variable with the unit attribute in the variable entity
- Click on "OK" and get the crash

Same problem on Ubuntu 10.04 running Umbrello on Gnome
After creating two entities, when creating a foreign key, Umbrello crashes when you press apply or save.
