--- Comment #2 from RJVB <rjvber...@gmail.com> ---
I think this happens because/when DebugSession::handleVersion() is called with
an empty QStringList argument.
Why that would happen I have no idea, possible it's related to commit
102f673c6ff1afe5b1ca9cb6faa0503663b96e16 ("LLDB plugin: check LLDB version
rather than lldb-mi version, which doesn't change frequently"). If that does
what I think it does it tries to invoke lldb, which may not be in the path.
Either way, returning early from handleVersion() works around the crash and
allows the debugger to function:
```
