Package: all KDE apps
Version: 1.92

When executing an application which uses SIGRTMIN and the application is
not 
linked with -lpthreads, SIGRTMIN is blocked. SIGRTMIN is normally equal
to 
32. The Linux Pthreads library however uses this signal for its own. It 
increments SIGRTMIN and all blocks the signal. After forking and execing 
another program the signal mask is still blocking SIGRTMIN(32 variant).
This is quite unexpected. Especially konsole and kdeinit should reset
the 
sigprocmask before calling exec(2).
