Error when debugging with Qt creator

[NewLegend]

My application compiles ok, but when I try to debug, I get:

"The inferior stopped because it received a signal from the operating system.
Signal Name: SIGSEGV
Signal Meaning: Segmentation fault"...

Look for one of the following possible causes of Segmentation Fault:
# buffer overflow
# using uninitialized pointers
# dereference NULL pointers
# attempt to access memory the program does not own
# attempt to alter memory the program does not own

From reading on google I think this has to do with remote debugging.
If so, someone said his problem was resolved when changing the firewall. (it's on this forum somewhere)

I forgot one more possible reason of Segmentation Fault: double deletion (take care with what you delete in destructors)
