Version:           3.2.2 (using KDE 4.2.2)
Compiler:          GCC4.4 
OS:                Linux
Installed from:    Debian testing/unstable Packages

I have read related bug reports, but the case is slightly different; installed juk from debian repositories. 
I have set juk to start in the kde autostart directory; when the environment 
loads, all apps in the directory start as expected except juk, below is the 
backtrace (debugging symbols installed): 

Application: JuK (juk), signal SIGSEGV

Reproduction is easy: set juk in the Autostart dir and after log in, juk crashes.
Expected behaviour: application should start normally.
