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

|
||
|
|
rebuild with gcc 4.4.2 did not help.
|
||
|
|
|
||
|
|
crash happens when kmail send mail window is destructed (you hit send mail
|
||
|
|
button)
