Summary: crash in signature assistant
Product: kdevelop
Version: 4.2.60
Platform: unspecified
OS/Version: Linux
Status: NEW
Severity: crash
Priority: NOR
Component: general
AssignedTo: kdevelop-bugs@kdevelop.org
ReportedBy: mail@milianw.de
Application: kdevelop (4.2.60)
KDE Platform Version: 4.7.3 (4.7.3)
Qt Version: 4.7.4
Operating System: Linux 3.1.1-1-ARCH x86_64
-- Information about the crash:
I've changed a signature and triggered the assistant then kdev crashed. Maybe
important: I did this before a few times and it worked just fine. The file
where the change should be done was not opened in the editor.
-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
