Comment 1 Andreas Pakulat 2009-09-17 11:08:20 UTC

If anything this backtrace shows a bug in Qt, however KCrash might have snipped too many frames hence we can't be sure. Apart from that there's no reproduction information.

Comment 2 David Nolden 2009-09-17 11:16:25 UTC

Why should it be a bug in Qt? More probably it's the output-view, or the multiple main window support. There is enough info in the backtrace to see where the crash happens (Thread 1).

@reporter But it would be useful to know what you do when this crash happens

Comment 3 Andreas Pakulat 2009-09-17 12:18:48 UTC

> Why should it be a bug in Qt?

I said "if anything". The reason is that it crashes in QObject::connect() which should not crash if I pass in two valid objects.

See, you're guessing yourself. That leads nowhere. Without more data this bugreport is simply invalid.

Comment 4 David Nolden 2009-09-17 12:25:55 UTC

Yeah, it's the "two valid objects" that is the critical point.. that one is more likely to cause problems than QObject::connect.

Comment 5 Scatterlogical 2009-09-17 14:01:15 UTC

Well, I have saved several more similar crash dumps if you'd like to see them. Although you may be right about it being a qt bug - I've discovered that kdevelop seems to be leaking memory severely with certain ui interactions (particularly with the menu) - which I assume causes the final crash, but it seems that other programs are repeatedly allocating ram in the same way, except I've just not had them crash the same. I'll be looking into it further tomorrow to confirm what's going on, then submit it as a qt bug if appropriate. In any case, I've attached the other dumps which might shed a bit more light, if want to be sure it's not a kdevelop bug.

Comment 9 Andreas Pakulat 2009-09-17 16:06:10 UTC

the first and last are totally unrelated. The second could maybe be the same cause as the inital backtrace. Could also be fixed meanwhile. Still, without more information there's nothing we can do.

this is valid as can be seen by the numerous duplicates, yet I still wonder how we could reproduce this and fix it...

Protect access of QAbstractItemDelegate pointer using a QWeakPointer.

The standard output view allows plugins to provide delegates and
also allows them to keep the ownership of them. While powerful, this
seems to be buggy and can lead to crashes in some cases.

Now we should properly detect the cases where we try to access an
invalid item delegate and output a warning instead of crashing.

It would still be interesting to know which plugin is responsible
for this bug.

Comment 15 Andreas Pakulat 2012-08-06 18:54:40 UTC

Does the WeakPointer help? I guess given 204399 its not really helping. But the same applies as I said in the other report.

Comment 16 Milian Wolff 2012-08-07 08:24:25 UTC

The weakpointer should prevent the crash shown here but of course it does not really "help" in the sense that 204399 is still valid and might result in the crash now instead. I have not yet found a reliable way to reproduce the crash shown here, so I can't be sure.

I agree that we will have to do something more radical as outlined in 204399 to fix this issue for good.

Git commit f5e397be7a8088a94814a488133d572dc4167f14 by Milian Wolff.
Committed on 07/08/2012 at 13:09.
Pushed by mwolff into branch 'master'.

Let the OutputView take ownership of a job's model and delegate.

This is required to ensure proper functionality of the views
when e.g. a plugin gets unloaded. Previously, this would trigger
crashes due to access of invalid model or delegate pointers.

Now the view will stay functioning even if e.g. the MakeBuilder
gets plugin gets unloaded after a project was compiled, or even
if you close a project while it is being built.

It is still safe to access both, the model and the delegate,
from inside a job as long as the job is running. When a view
gets closed, the job gets cancelled anyways.

Sadly, this is an ABI break and thus cannot be backported to
the KDevplatform 1.4 branch...

Committed on 07/08/2012 at 13:50.

Let the OutputView take ownership of the make output delegate.

This is basically the fix for the two bugs below that does not
require any ABI break and can thus be done in the 1.4 branch.
