Application: kdevelop (4.0.60 (using KDevPlatform 1.0.60))
KDE Platform Version: 4.4.75 (KDE 4.4.75 (KDE 4.5 >= 20100505)) (Compiled from sources)
Qt Version: 4.7.0
Operating System: Linux 2.6.33-gentoo-r1 x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
- What I was doing when the application crashed:
I was just deleting some code from a line in a function when I got this crash. Could be the same random crash I get doing the same thing.

The crash can be reproduced some of the time.

Reported using DrKonqi

Comment 1 Andreas Pakulat 2010-05-09 11:21:54 UTC

Either a bug in kate or qt, re-assigning to kate for now maybe they've seen this already before.

Comment 2 Dominik Haumann 2010-05-23 00:56:49 UTC

This is very similar to bug #194111, instead of addRow here we have removeRow...

Comment 3 Christoph Cullmann 2010-07-05 15:14:26 UTC

The code completion model looks corrupted, guess this is a result of incorrect use while filling in in kdevelop. Never seen such crash with single-threaded kate word completion, therefor assigning back.

Comment 4 Milian Wolff 2010-09-08 23:07:05 UTC

can someone reproduce this?

Comment 5 Milian Wolff 2011-03-02 19:04:42 UTC

Created attachment 57614 [details]
New crash information added by DrKonqi

kdevelop (4.2.60) on KDE Platform 4.6.00 (4.6.0) using Qt 4.7.1

used kdev for some hours, triggered code completion => crash

Just experienced the same, using KDevelop/KDevplatform/Kate from Git master.

Comment 7 Kevin Funk 2013-11-13 14:04:31 UTC

Found a code snippet where this is easily triggered:

"""
void* foo() { return 0; };
int main()
{
    void* v = foo();
}
"""

Put the cursor after 'foo' inside main. Then invoke the completion pop-up (Ctrl+Space), then press Backspace  three times => Crash.

I'm hitting this quite often, raising importance.

kdevelop(28183)/Kate KateCompletionModel::parent: Couldn't find parent for index QModelIndex(0,0,0x436d590,KateCompletionModel(0x436e840) )  

the kate completion model should be fixed by running it with a ModelTest hooked up

Comment 9 Dominik Haumann 2013-11-13 16:03:05 UTC

Cannot reproduce in KWrite.

@Milian, Kevin: If you can reproduce, can you investigate + provide a patch?

Comment 10 Milian Wolff 2013-11-13 16:25:45 UTC

Yeah of course you cannot reproduce in KWrite, you need fancy code completion which so far only KDevelop provides afaik.

I reassigned this only to kate since it's the completion model there which is broken. We are the consumers and do feel responsible :) Question is when we find the time to rewrite / fixup the code completion model...

Comment 11 Kevin Funk 2013-11-13 16:41:30 UTC

I'm on it. The fix is relatively simple: Avoid using reset() inside KateCompletionModel. KateCompletionWidget is trying to call QAIM::setCurrentIndex during a model reset (i.e. when model indices got invalid without having notified QAIM about it).

I have a local patch where I used {begin,end}ResetModel instead with a couple of cleanups which apparently fixes this crash. I'm testing it for a while to make sure it's not causing regressions.

Git commit b768749230872b5acf0e2816dd855409f6d70733 by Kevin Funk.
Committed on 11/12/2013 at 23:51.
Pushed by kfunk into branch 'master'.

Fix assert in ~QPersistentModelIndex

KateCompletionWidget may call QAIM::setCurrentIndex during a reset of
the model, inside KateCompletionWidget::modelContentChanged(). At this
point, model indices are invalid, but QAIM wasn't informed about it.

The main problem is that KateCompletionModel doesn't use the
(relatively) new {begin,end}ResetModel blocks to make persistent model
indices invalid when we start resetting the model. Instead reset() is used
*after* we have reset the model. However, KateCompletionModel may emit
contentGeometryChanged too early (before a reset()) and hence triggering
QAIM::setCurrentIndex while QAIM is still referencing now invalid
persistent model indices.

Other changes:
Remove contentGeometryChanged. Instead, use layoutChanged() and
modelReset() signals to react to model changes.

This also ports KateCompletionModel away from deprecated QAIM methods
such as QAIM::reset()

Comment 16 Michael Palimaka 2014-02-26 17:12:03 UTC

Is this a candidate for backporting to KDE/4.12?

Comment 17 Kevin Funk 2014-02-27 09:52:59 UTC

I'd leave this up to the Kate maintainers -- for me the patch worked fine, so i'm fine backporting it if needed.
