Description claas.koehler 2011-03-30 13:25:28 UTC

Application: kdevelop (4.2.0)
KDE Platform Version: 4.6.00 (4.6.0) "release 6"
Qt Version: 4.7.1
Operating System: Linux 2.6.37.1-1.2-desktop x86_64
Distribution: "openSUSE 11.4 (x86_64)"

-- Information about the crash:
- Source file of a project opened without problems
 - Adding an additional comment line to the file resulted in a crash of KDevelop
 - Restoration of the source file after the crash causes KDevelop to crash again
 - Bug is reproducible with the source file in question, but I have not yet encountered similar behaviour with any other source file

The crash can be reproduced every time.

The file is part of a larger project. When editing the file in a new project, containing just this file, everything is fine. So there seems to be little gain in providing the single file.

Furthermore as additional information: I ran KDevelop under gdb, and the problem could not be reproduced anymore. Rather mysterious.
