           Summary: Crash after pressing the mini-button inside the
                    "Source" tab.
           Product: kdevelop
           Version: 4.1.0
          Platform: Compiled Sources
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdevelop-bugs@kdevelop.org
        ReportedBy: forestgril@o2.pl


Application: kdevelop (4.1.0)
KDE Platform Version: 4.5.1 (KDE 4.5.1) (Compiled from sources)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-25-generic i686
Distribution: Ubuntu 10.10

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

The only thing I did was selecting the "Source" tab in the upper right corner
with several open source files and no project specified, and checking the
functionality of the little button (don't know its name and purpose) which ise
inside (on the right) of this (Source) tab. After that, the program immediately
crashed.
