            Bug ID: 302760
          Severity: crash
           Version: 4.3.1
          Priority: NOR
          Assignee: kdevelop-bugs@kdevelop.org
           Summary: KDevelop crashes on startup when recovering document
    Classification: Unclassified
                OS: Linux
          Reporter: mw_triad@users.sourceforge.net
          Hardware: Fedora RPMs
            Status: NEW
         Component: general
           Product: kdevelop

Application: kdevelop (4.3.1)
KDE Platform Version: 4.8.3 (4.8.3)
Qt Version: 4.8.2
Operating System: Linux 3.4.3-1.fc17.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed:
Started KDevelop, attempted to recover changes made from previous crash.

I seem to have gotten KDevelop into a situation where I can reliably reproduce
this crash. Unfortunately, the relevant files are not something I am at liberty
to share AFAIK. However, I may be able to help with diagnostics if someone can
work with me...

The crash can be reproduced every time.

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