            Bug ID: 304672
          Severity: crash
           Version: 4.3.1
          Priority: NOR
          Assignee: kdevelop-bugs@kdevelop.org
           Summary: KDevelop crash when reopening a file
    Classification: Unclassified
                OS: Linux
          Reporter: titombitel@wp.pl
          Hardware: openSUSE RPMs
            Status: UNCONFIRMED
         Component: general
           Product: kdevelop

Application: kdevelop (4.3.1)
KDE Platform Version: 4.9.00 "release 555"
Qt Version: 4.8.2
Operating System: Linux 3.1.10-1.16-desktop x86_64
Distribution: "openSUSE 12.1 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
1. Closed a header file from the only current project without saving it.
2. Reopened it from the fast open menu on the right (this where you can open
files, classes, etc. This that looks like a textfield. It would be much easier
to name it if i was able to run KDevelop now).
3. It crashed.
- Custom settings of the application:
I changed the white spaces behavior (to tabs only but KDevelop still forces
normal spaces when i pass arguments to a function in multiple lines, that will
be another bug report maybe)

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