Operating System: Linux 2.6.31-ARCH i686
Distribution (Platform): Archlinux Packages

-- Information about the crash:
kde 4.4 beta1: 
steps to reproduce: 
alt f2 to bring krunner, start typing app name (netbeans in my case), so eg on 'netb' netbeans and some more show up, continue typing, when i finish the name 'netbeans' the app crashes (still not clicking anything)

maybe some list of possible choices to show is empty and thaht causes the crash? 

thank you very much

Comment 1 Jacopo De Simoi 2009-12-17 18:40:56 UTC

This is in fact a glibc bug, due to a race in free(), it should be fixed in 2.11.1
