Description Bill Lorton 2009-05-29 18:57:41 UTC

Version:            (using KDE 4.2.3)
OS:                Linux
Installed from:    Fedora RPMs

This has been happening since I started using Fedora Core 10 (about 6 months).  If I just start 2 of the 3 applications, or pause between the launches of the 3 applications the crash does not occur.  But every time I launch those 3 applications quickly the crash occurs.

Firefox 3.0.10
Pidgin 2.5.5-1.fc10
KMail 1.11.3

Application: Plasma Workspace (plasma), signal SIGSEGV

the important part of the backtrace, Thread 1, is missing. can you re-post? (it looks like it got cut off there)
