Description Iván Sánchez Ortega 2004-03-07 15:22:28 UTC

Version:           3.2.0 (using KDE 3.2 BRANCH >= 20040204,  (testing/unstable))
Compiler:          gcc version 3.3.3 20040125 (prerelease) (Debian)
OS:          Linux (i686) release 2.4.24-1-k7

Something is wrong with embedded Kfind... Please do the following:

- Open Konqueror, browse to a local directory with several files
- Show embedded Kfind (tools -> search files)
- Do a search query that should last some time (a quick search won't reproduce this one). A query for a file contaning some text will do fine.
- *WHILE* Kfind is searching, and some results are already shown, click on one of them. A *.html will do fine.
- See how Konqui switchs to the embedded viewer mode, then crashes.

I got this one while searching for some words in a wget-ted web.

This is with Konqui CVS 20040215.

I couldn't get a backtrace (compiled w/o debug simbols :-(  )

Comment 1 Tommi Tervo 2004-10-21 16:18:08 UTC

Cannot reproduce. Could you build with debug symbols if you still can reproduce this crash with 3.3.x konqueror?

Comment 2 Iván Sánchez Ortega 2004-10-21 16:53:50 UTC

> Cannot reproduce. Could you build with debug symbols if you still
> can reproduce this crash with 3.3.x konqueror?

While trying to reproduce (in 3.3.0), I found that launching an embedded 
kfindpart directly crashes Konqueror :-/

(In order to do so, I went to Kcontrol to configure file types & associations, 
in order to be able to "open" a inode/directory with kfindpart).

drkonqui shows me the following backtrace:

Comment 3 Iván Sánchez Ortega 2005-04-12 12:04:29 UTC

kfindpart still crashes in my computer in KDE 3.4.0. Open konqueror, switch to kfindpart, and kaboom!. Relevant portion of the backtrace follows :

Comment 4 lexual 2006-08-09 01:07:02 UTC

confirming for 3.5.4

Comment 5 Frank Osterfeld 2006-08-22 21:11:39 UTC

Lexual: Can you provide a recent backtrace (as the report is older and the bt may have changed)? Which view mode do you use (View->View Mode in the menu).

Comment 6 Raúl 2006-12-07 13:46:59 UTC

I also notice this behaviour on 3.5.5. My view is detailed list view. I attach a recent backtrace:

Comment 7 Sune Vuorela 2006-12-07 20:36:25 UTC

Hi! I have also easily reproduced it following the steps described here.

I use iconview view.

Comment 8 Mathieu Parent 2007-02-03 22:13:29 UTC

Is this related ? :

- Open Konqueror, browse to a local directory with several files
- Show embedded Kfind (tools -> search files)
- Do a search query that should last some time (a quick search won't reproduce this one). A query for a file contaning some text will do fine.
- *WHILE* Kfind is searching, and some results are already shown, switch display type (hope this is well translated, french is 'Type d'affichage') to another (icon, detail, ...)
- See how Konqui crashes.

(haven't find any bug #)

Comment 9 Mathieu Parent 2007-02-03 22:15:13 UTC

sorry, last comment was konqueror 3.5.5 (on debian etch = 4:3.5.5a.dfsg.1-5)

Comment 10 Tommi Tervo 2007-11-01 21:46:20 UTC

*** Bug 151714 has been marked as a duplicate of this bug. ***

Comment 11 FiNeX 2008-05-04 23:31:58 UTC

Cannot reproduce on 3.5.9.
On KDE 4 kfind has not been integrated yet.
Kfind on KDE 4 (trunk r802881) doesn't crash opening files while the search is not finished.

It seems as fixed.

Comment 12 Frank Reininghaus 2008-09-10 22:06:46 UTC

It still crashes 3.5.10 for me with the same backtrace as in comment 6. Not sure what to do with this one though because I don't know if this functionality is ever going to be implemented in KDE 4.

Comment 13 FiNeX 2009-08-20 22:33:59 UTC

Being not implemented on KDE 4 and being KDE 3 no more mantained. Maybe it is better to set this as "unmantained".
