SDR usbtmc transport segfaults when given a bad path
Fresh build of clean repo at b7fd0e9b, to reproduce:
- Open ngscopeclient
- Add > SDR > Connect...
- Select
usbtmctransport - Enter an arbitrary path such as
/dev/null(I can't test against one that should work because I don't even know what usbtmc is) - Add
- Segfault
