Comment 1 Andreas Pakulat 2010-05-26 11:03:45 UTC

Well unfortunately the backtrace is useless. Please run kdevelop in valgrind:

KDEV_SESSION=blah valgrind track-origins=yes kdevelop.bin

Re-Assigning to kate as autobrace is a kate-plugin.

Comment 2 Milian Wolff 2010-05-26 13:25:35 UTC

I could reproduce, will try to fix it. I'd appreciate it, if you could provide me with a valgrind log.

Bye

Comment 3 Andreas Pakulat 2010-05-29 02:14:03 UTC

*** Bug 239904 has been marked as a duplicate of this bug. ***

Comment 4 Dominik Haumann 2010-06-14 01:23:13 UTC

Can this be fixed for KDE 4.5? Otherwise it's maybe better to entirely disable autobrace plugin for 4.5?

Comment 5 Milian Wolff 2010-06-14 03:29:34 UTC

I'll have to look at it tomorrow. don't disable it for now please, I have to use that plugin :)

Comment 6 David 2010-07-31 15:59:34 UTC

Created attachment 49711 [details]
New crash information added by DrKonqi

same as report that this is attached to : 
KDevelop 4.0 // KDE 4.4.5 
Editor--> Configure Editor/Settings --> Extensions --> Enable AutoBrace --> OK/Apply --> Crash

Comment 7 Milian Wolff 2010-07-31 16:43:29 UTC

some more info:

valgrind output:
http://pastebin.com/hc0Be7QJ

And the CLI gets spammed with messages like these after hitting apply:
kdevelop(16813) EventListener::eventFilter: User of KWidgetItemDelegate should not delete widgets created by createWidgets! 

Note: With KDE 4.4.95 it's not crashing anymore for me. I'll send a mail to kde-core-devel and ask their assistance.

Comment 8 Milian Wolff 2010-07-31 16:54:19 UTC

funny, it does crash when not run inside Valgrind...

Comment 9 Milian Wolff 2010-07-31 17:20:31 UTC

Reassigning to KDevelop as this behavior is only exhibited there. Maybe our menu restructuring is the culprit, have to investigate...

But for me KDevelop crashes when I change any KTextEditor plugin, i.e. either enable or disable it.

Comment 10 Milian Wolff 2010-09-06 17:54:35 UTC

*** Bug 243789 has been marked as a duplicate of this bug. ***

Comment 11 Milian Wolff 2010-09-06 19:24:58 UTC

More information from running valgrind on a different machine. I don't get how this is happening. Assigning to kdelibs for help. If it's not there, maybe even a bug in Qt? Otherwise I'm lost...

*** Bug 250894 has been marked as a duplicate of this bug. ***

Comment 13 Christoph Feck 2010-10-13 17:58:36 UTC

Closing this as a duplicate of bug 170806 because the backtrace indicates that the XMLGUI client list contains stray pointers.

If you are experiencing toolbar or shortcut related crashes again with KDE 4.5.3 or later, please create a new bug report.
