+there appeared some kind of leak or memory overwrite, or double destruct, can't
+track down where it came from, only thing done (to my knowledge) was to rebuild
+kde packages due newer dependencies in distro. maybe gcc overoptimizes, but
+rebuild with gcc 4.4.2 did not help.
+
+crash happens when kmail send mail window is destructed (you hit send mail
+button)

+Program received signal SIGSEGV, Segmentation fault.
