Comment 3 Frank Reininghaus 2012-09-02 13:59:31 UTC

Thanks for the bug report! This looks pretty much like bug 304524, which has been fixed recently. However, I'm a bit confused by Jekyll's backtrace, which looks different from the one I'm getting when I revert the fix for that bug, so I'm wondering if there is something else that needs to fixed.

@Jekyll: Did you get that crash with a recent checkout of the 4.9 or master branch, or with a version that does not contain the fix for 304524 yet?

Comment 4 Jekyll Wu 2012-09-02 14:21:13 UTC

@Frank

I built dolphin based upon commit 6892d39d, which comes after the commit for bug 304524 .

It is easy to reproduce. Just prefer F2 to start inline renaming, then press F5.

Comment 5 Frank Reininghaus 2012-09-03 11:31:43 UTC

Thanks Jekyll, I can indeed reproduce the crash with the current master branch. It looks like the items are first removed from the model, and then DolphinView tries to start the renaming, which fails because there is no valid KFileItem any more.

Comment 6 Frank Reininghaus 2012-09-11 17:43:11 UTC

Strange, I can reproduce the crash on one machine, but not on the other one. Maybe it's because the order in which some slots are invoked by the same signal (which is undefined) matters here.

Anyway, I've got a patch that fixes the crash for me.

Comment 7 Frank Reininghaus 2012-09-11 17:46:29 UTC

Git commit ea3ed1d9e5409af7d374c66d53dbb2ff68a5fe70 by Frank Reininghaus.
Committed on 11/09/2012 at 19:43.
Pushed by freininghaus into branch 'KDE/4.9'.

Fix possible crash when refreshing the view while renaming inline

It is not reproducible on every machine for me, but it seems that it can
happen that DolphinView's slot slotRoleEditingFinished() is invoked
after the items have already been removed from the model. In that case,
we have to return from the slot immediately to prevent a crash.
FIXED-IN: 4.9.2

dolphin (2.1) on KDE Platform 4.9.1 using Qt 4.8.2

-renaming a file, then click back to change dolphin's pannel.
-dolphin crash.
