Description Alex Fiestas 2012-04-29 17:53:41 UTC 
Application: dolphin (2.0.95)
KDE Platform Version: 4.8.2 (4.8.2) (Compiled from sources)
Qt Version: 4.8.1
Operating System: Linux 3.3.4-1-ARCH x86_64

-- Information about the crash:
I was filtering items via Ctrl+it when it happens. I can reproduce this bug quite often and it only happens if I start filtering by the begining of the word, for example:

/content2
/content1
/xxxxfoo

If I open the filter and I type xxx it will crash, instead if I write foo it won't crash.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Dolphin (dolphin), signal: Aborted

Comment 1 Peter Penz 2012-04-29 19:25:30 UTC 
Alex, do you probably have a directory where the crash is reproducible in a reliable way, that you can attach as zip-file to this report? Do you have the details-view enabled with sub-trees open when filtering? In the end I guess it should not be tricky to fix (the ASSERT gives already a hint whats going wrong), but I need to be able to reproduce it first and it looks like the way I'm doing the filtering never triggers this issue... :-/
Comment 2 Alex Fiestas 2012-04-29 22:01:14 UTC 
It is an ftp folder, and I do the filtering action quite quickly after I see the first item,

Will check if I can spot any other pattern.

New crash information added by DrKonqi

dolphin (2.0) on KDE Platform 4.8.2 (4.8.2) using Qt 4.8.1

- What I was doing when the application crashed:
Dolphin crashed when removing with Backspace filter phrase. It seems to try to find the proper result for every intermediate phrase which obviously changed quite fast (as I keep pushing Backspace).

Resetting assignee to default as per bug #305719
Comment 5 Alex Fiestas 2013-02-24 22:21:03 UTC 
This bug was fixed iirc, should we close it?
Comment 6 Frank Reininghaus 2013-02-25 08:32:19 UTC 
There were quite a few changes in that function, so it could be that it is fixed. Considering that we did not get any reports for Dolphin >= 2.1, this seems indeed likely. I would prefer if we knew what exactly triggered the crash in the first place, so we could add a unit test and prevent that it reappears at some point, but I guess we can really close it then. Thanks for your help.
