Description Greg Ratner 2012-11-04 20:43:27 UTC
The debugger crashes when watches that are not in scope are deleted on 2nd delete.

Steps to reproduce:

1. Add variables to watch (3-5)
2. Hit a breakpoint
3. Delete watches that are not in current scope. Second delete causes a crash

this has been fixed in git (probably won't make it in until 3.0.6)

Got it, thanks. It's really pissing me off because crashes erase breakpoints. :)
