            Bug ID: 375728
           Summary: konqueror crashes after switching windows
           Product: konqueror
           Version: unspecified
          Platform: Gentoo Packages
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: konq-bugs@kde.org
          Reporter: kavol@seznam.cz
  Target Milestone: ---

Application: konqueror (4.14.24)
KDE Platform Version: 4.14.24
Qt Version: 4.8.6
Operating System: Linux 4.4.39-gentoo x86_64
Distribution (Platform): Gentoo Packages

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

I was browsing aliexpress.com, then I switched to another app. When trying
toswitch back to konqueror, I have found there is DrKonqui waiting instead ...
Seems pretty reproducible after logging onto aliexpress.com.

The crash can be reproduced every time.

-- Backtrace:
Application: Konqueror (konqueror), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
