           Summary: Crash when closing output tabs very quickly
           Product: kdevelop
           Version: 4.2.60
          Platform: Compiled Sources
        OS/Version: Linux
            Status: NEW
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdevelop-bugs@kdevelop.org
        ReportedBy: aspotashev@gmail.com

Application: kdevelop (4.2.60)
KDE Platform Version: 4.6.3 (4.6.3) (Compiled from sources)
Qt Version: 4.7.3
Operating System: Linux 2.6.38 x86_64
Distribution: "Gentoo Base System release 2.0.2"

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

1. run my C++ application (that I develop in KDevelop) a few times
2. click the "close tab" button very _quickly_ to close a few output views.
About 6 clicks per second is enough.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
