Description PC LX 2015-12-03 12:12:55 UTC

Application: plasmashell (5.4.95)

Qt Version: 5.5.1
Operating System: Linux 4.3.0-desktop-2.mga6 x86_64
Distribution: "Mageia 6"

-- Information about the crash:
- What I was doing when the application crashed:

Aplication Launcher causes Plasma Shell to crash when searching or viewing history tab.

- Steps To reproduce:

1) Click on the Application Launcher icon in the panel.
2) Click on the "Histórico" tab (probably "History" or "Historic" tab in english locale).

Or

1) Click on the Application Launcher icon in the panel.
2) Click on the search ("Escreva para pesquisar..." in pt-PT locale, probably "Write to search..." or "Type to search" in english locale) and start typing something.

That is it. The Plasma Shell will crash every time one the the above is done.

- Unusual behavior I noticed:

Plasma Shell crashes.

Can you start plasmashell from the terminal and post the output so that we can see why the sql driver fails?

Comment 3 Ivan Čukić 2015-12-15 17:31:02 UTC

This looks like the culprit behind the issue - there are different Qt components from different Qt versions.

Comment 4 PC LX 2015-12-16 10:21:31 UTC

Thanks. it seems then to be a distro specific issue. I've created a bug report in Mageia's bug tracker.

Comment 5 Francisco Cribari 2016-08-23 14:51:05 UTC

I am having the same problem with KDE + Arch. See https://bugs.kde.org/show_bug.cgi?id=366022 . Plasma crashes often when I typing to search for an application in the Application Launcher. Interestingly, that does not happen when I do so in the Application Dashboard. Have you found a solution to the problem?

Comment 6 Ivan Čukić 2016-08-23 15:02:24 UTC

@Frabcisco

These are unrelated issues.
