            Bug ID: 297178
          Severity: crash
           Version: 4.3.0
          Priority: NOR
          Assignee: kdevelop-bugs@kdevelop.org
           Summary: KDevelop crashed after "Line too long" error message
    Classification: Unclassified
                OS: Linux
          Reporter: unclemarcus91@hotmail.com
          Hardware: Fedora RPMs
            Status: UNCONFIRMED
         Component: general
           Product: kdevelop

Application: kdevelop (4.3.0)
KDE Platform Version: 4.8.1 (4.8.1)
Qt Version: 4.8.0
Operating System: Linux 3.2.7-1.fc16.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed:
Opened my Rosegarden project in KDevelop, did a quick search for a source file
through the "Quick Open" box at the top, double-clicked the file in search
results, got the following message:

The file
/home/[username]/projects/rosegarden/src/gui/editors/matrix/MatrixView.cpp was
opened and contained too long lines (more than 1,024 characters). Too long
lines were wrapped and the document is set to read-only mode, as saving will
modify its content.

...and after clicking OK without ticking "Don't ask again", it crashed.

Said source file indeed does have a line longer than 1024 characters as a
result of a hacky fix.

The crash can be reproduced some of the time.

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