New crash information added by DrKonqi
kate (3.10.1) on KDE Platform 4.10.1 using Qt 4.8.4
- What I was doing when the application crashed:
First crash appeared when using Quick Open Session once.
However, I can reproduce this with fast repeating of using Quick Open Session.

I could try, but I need instructions on how to do a valgrind trace. Created attachment 78218 [details] Kate Valgrind Trace Nvm, found this: http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_with_Valgrind Attached is a valgrind trace. However, Kate crashed here right after the session manager. Applications that use JIT, i.e. anything with JavaScript like Kate, KDevelop, QML, ... will need the --smc-check=all flag passed to valgrind. The valgrind log seems unrelated to this crash.

Kate Valgrind Trace, 2nd try
Ok, here is a trace with the smc-check flag.
Took about 15 quick open sessions to crash kate, but it finally did.
This is what we wanted, thanks: Even better: can you install debug symbols so that we can look inside KActivities as well?

1 if (!m_activityResources.contains(view)) {
2 m_activityResources[view] = new KActivities::ResourceInstance(view->window()->winId(), view);
3 }
4 m_activityResources[view]->setUri(doc->url());
I guess, m_activityResources.contains(view) is true, therefore the if is not executed.
m_activityResources[view] then probably returns a dangling pointer to KActivities::ResourceInstance so that setting the QUrl fails.
So we need to check whether this is really what happens. Usually, the hash should NEVER contain view, since the view is just created several lines above:
KTextEditor::View *view = (KTextEditor::View *) doc->createView (activeViewSpace()->stack);
So this code is wrong anyway, and line 1 should be an assert:
Q_ASSERT(!m_activityResources.contains(view));
Anyone who can reproduce: Can you check this?

New crash information added by DrKonqi
kate (3.10.1) on KDE Platform 4.10.1 using Qt 4.8.3
- What I was doing when the application crashed:
Switching sessions using 'quick switch'
- Custom settings of the application:
Konsole-part is open in at least one of the sessions.
I take it that the bug was fixed already in 4.10.2, but I will check again after updating to this version.

Bastian, it's fixed in KDE 4.10.2. So just update. We don't need further info on this report. |
