Summary: KDevelop4 Crash when typing and then quickly
backspacing
Product: kdevelop
Version: unspecified
Platform: Unlisted Binaries
OS/Version: Linux
Status: NEW
Severity: crash
Priority: NOR
Component: general
AssignedTo: kdevelop-bugs@kdevelop.org
ReportedBy: astromme@chatonka.com
Application that crashed: kdevelop
Version of the application: 3.9.93 (using KDevPlatform 0.9.93)
KDE Version: 4.2.87 (KDE 4.2.87 (KDE 4.3 >= 20090519))
Qt Version: 4.5.1
Operating System: Linux 2.6.28-11-generic x86_64
Distribution: Ubuntu 9.04
What I was doing when the application crashed:
It's sometimes hard to reproduce, but the following seems to trigger it:
Have a document loaded with the DUChain active
Start typing something where command completion would be in effect
After finishing a subword, quickly press backspace (i.e. a misspell, etc...)
*crash*
