Programas Terminan Incorrectamente. Señal 11, SIGSEGV

[Starvin Marvin]

Hola, les escribo porque recien he instalado Kubuntu y os voy a
comentar una cosa que me pasa a menudo.
 Algunos programas cuando los cierro, en vez de cerrarse
correctamente, se cierran devolviendo un 11 (SIGSEGV) y me
 salta le "manejador de fallos de KDE" diciendome eso, que la
aplicacion fallo y provoco la señal 11. Es curioso, porque
 me ha pasado con el Kopete, amaroK, Kaffeine y con el Konqueror, pero
no me pasa siempre. Y encima solo es eso, un
 fallo sin importancia (o a mi me lo parece) porque mientras uso esos
programas todos funcionan correctamente, pero
 es cuando los cierro cuando se produce el fallo.
 
 Adjunto el trazado inverso por si os sirve de algo.
