            Bug ID: 495845
           Summary: Searching application (KRunner, Plasmashell) quits for
                    some queries while the Browser Integration plugin is
                    enabled
    Classification: Plasma
           Product: plasma-browser-integration
           Version: unspecified
          Platform: Arch Linux
                OS: Linux
            Status: REPORTED
          Severity: crash
          Priority: NOR
         Component: Firefox
          Assignee: k...@privat.broulik.de
          Reporter: dump+kdeb...@karcsesz.hu
  Target Milestone: ---

SUMMARY
Whenever searching for a select few keywords in KRunner or through Application
Launcher's search field, the given application cleanly exits without logging
anything or generating a crash dump.

I have quite a lot of tabs open in Firefox (manually running a query against
the extension's DBus service makes QDBusViewer lag), so my hunch is this either
has to do with a message size limit or the request timing out.

Disabling "Browser Tabs" from Plasma Search works around the issue.

STEPS TO REPRODUCE
1. (probably) have a lot of open tabs in Firefox (I have a bit over 1000, no I
do not have a problem >c<)
2. Install Plasma Integration 1.9.1 and have Browser Tabs enabled in Plasma
Search settings
3. Experiment with KRunner while having `journalctl --user -f` running
4. On some search terms KRunner exits without a single logged error
5. Try the same with the builtin search for Application Launcher
6. plasmashell quits without any automatic recovery taking place

OBSERVED RESULT

```
nov 05 16:03:25 Littlepip systemd[1005]: Started KRunner.
nov 05 16:03:25 Littlepip krunner[7829]: Connecting to deprecated signal
QDBusConnectionInterface::serviceOwnerChanged(QString,QString,QString)
nov 05 16:03:32 Littlepip systemd[1005]: plasma-krunner.service: Consumed 844ms
CPU time, 177.9M memory peak.
```

EXPECTED RESULT
Plasma Search either truncates the response and returns less precise results or
scolds the user for having too many open tabs.
