Description Pedro Veloso 2009-06-10 21:15:12 UTC 
Version:            (using Devel)
OS:                Linux
Installed from:    Compiled sources

When pressing F2 KDE brings the "rund dialog" which appears to be called KRunner. I use this dialog a lot, but it crashes whenever there is list of result and I scroll down. 

Example scenario :

I press F2 to bring KRunner. I type "firefox" and I see twice "Run firefox" and a third option saying "Firefox (Web Browser)" , it think the problem is that it is generating 2 "Run firefox" . If I scroll down to the third, the application crashes. In this case is not that annoing, because they all did the same, open firefox, but in some cases there are diferent options.

> Sometimes the list I refered only contain one "Run firefox". Strange, since I don't seem to do anything different.

Here's what I have selected in the options menu of KRunner: 

"Applications" , "Bookmarks", "Calculator", "Command Line", "Contacts", "Desktop Sessions", "Kate Sessions", "Konsole Sessions", "Locations", "Nepomuk Desktop Search", "Places", "PowerDevil", "Recent Documents", "Unit Converter", "Web History", "Web Shortcuts" . Yeah, there's plenty of options in there, but I think most of them were already checked by default. 

Also, here's the "crash dump" the application generated : http://www.mediafire.com/?etlwkvn11hj

Comment 2 Dario Andres 2009-06-10 21:40:53 UTC 
- What is your KDE4 version? (SVN revision/branch)

If you can reproduce the crash at will, may you read http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports and post a complete backtrace here? You need to install the debug symbols package for kdebase-workspace.

Thanks
Comment 3 Pedro Veloso 2009-06-11 12:09:41 UTC 
I'm using opensuse 11.1, and using the factory repositories of KDE, in the package manager it is numered KDE 4.2.90 . I'll install the debug packages then, and post here the backtrace.
Comment 4 Jacopo De Simoi 2009-06-11 15:24:04 UTC 
by "scroll down" you mean just select the third item in your list?
Comment 5 Pedro Veloso 2009-06-11 17:06:11 UTC 
"by "scroll down" you mean just select the third item in your list?"
 -> Yes, I press the down arrow on the keyboard to go to the third option, and once it get there it crashes, I don't even have to press the Enter key.

OK, I've installed the debug packages, and here's the backtrace :

Comment 6 Pedro Veloso 2009-06-15 21:09:11 UTC 
One little add up, I noticed just now ( sorry for doesn't telling this later ). I'm using the "Task Oriented" user interface option. I've switched to the other one, which I believe it's the default one, and it doesn't show the 3 options, but the correct 2, and thus it's not crashing, so the bugs is with the "Task Oriented" GUI.

On the image attached you can see how horizontal list and the vertical one do not keep coherent selected elements

also affected

kde sc 4.4, binary kubuntu 9.10 packages


in quicksand mode sometimes two lists appear (a vertical one to the right of quicksand and a horizontal one within quicksand); can use the arrow keys to navigate through them but they never stay in sync but do appear to show the same results

New crash information added by DrKonqi

In QuickSand mode

entered a search that pulled up 29 results

see two lists
: horizontal one inside quicksand and a 
: vertical one outside of quicksand

when the out outside of quicksand appears, i can use the up/down to cycle through the items; and still left/right to cycle through the other

but the selected item does not stay in sync (scrolling one does not scroll the other)



(kubuntu 9.10; kdesc4.4 binaries)
