Comment 1 Sebastian Sauer 2011-09-21 13:06:33 UTC
I am not 100% sure there (cause I was never able to reproduce that problem) but iirc we fixed that crash already a while ago. But then the bug-report says beta1 which was just released what means the problem would still be present...
Comment 2 Camilla Boemann 2011-09-21 13:09:14 UTC
I've never been able to produce that crash either :(

Doc you build calligra yourself?

it may be you have not deleted a former installation

I am using official Gentoo ebuilds which should basically guarantee to remove old files when updating a package. Configuration files are excluded, of course.

I am wondering if the problem may be related to that I am still using KDE 4.6.5? It is the latest stable KDE release for Gentoo.

I'll try to compile Calligra with debug flags enabled to see if I get more information...
Comment 6 Camilla Boemann 2011-09-27 09:27:51 UTC
I'm using 4.6.5 too so that is not it
Comment 7 Camilla Boemann 2011-10-09 11:38:04 UTC
It looks like it a QObject being deleted twice but since i don't get the crash there i no way for me to fix it
Comment 8 Camilla Boemann 2011-10-09 11:41:56 UTC
actually the
    delete m_toolSelection;


in the text tool destructor looks wrong as it's a qobject

I'm can't see if a deleteLater or just not deleting is the right fix

I can compile and test the code on my machine. Can you please send me a patch or some instructions what to change?

Even if Calligra does not crash in your case, using a tool like Valgrind should find the illegal delete?

Comment 11 Camilla Boemann 2011-10-26 07:39:15 UTC
ah no that can't be it

it crashes on deleting widgets, so it must be the option widgets then

Git commit 0aa702d9466251405162f55eea86c128bbf474f8 by C. Boemann.
Committed on 26/10/2011 at 09:43.
Pushed by boemann into branch 'master'.

Don't delete widgets that have this as parent - Qt will take care of that
 Deleting them just leads to crashes
