segmentation fault

[mattia]

When i call the process, for example RDP i can see the virtual terminal opening on my screen so i think the slot connected to the process are called, I've tried to print a string into the QTextBrowser to see if i'm really jump into that slot and i'm able to print it ...

EDIT: maybe the signal is not emitted by callApplication but by QProcess, given that i'm trying to hook a signal (error) that it is emitted by another slot called by QProcess, in this case mi connect definition is not valide. Is it possible?
