DebuggerDriver crashes CB <<- Stop Debugger, close App

CB rev 3516, gcc 3.4.5-mingw, gdb 6.3

Debug-Session, app is free running...
When I stop the Debugger clicking the Stop-Button nothing happens (visibly), the App-Window stays active. 
When I close the app afterwards, CB crashes (SIGSEGV).

Note: this does not happen, when the debugger is in break-mode, stepping through. Stopping the debugger works as expected then, all is fine.

Here's the bt from crashreport and 2 detailed bt's from inside CB:

For my guess on it: the debugger-instance is destroyed but still used because the gdb-process is not closed/hanging and producing output.

Ubuntu Edgy, wxGTK 2.6.3p2, rev 3564, gdb 6.4.90-debian

I tried to reproduce this but I got a SIGSEGV earlier, when I click the Abort button. I don't know if it's the same bug but Debugger is definitely crashing.
