Regression: v1.4.1 causes an exception, v1.4.0 works
Describe the Issue v1.4.1 and above cause an exception when connection to my camera.
To Reproduce Execute the sample code
Sample Code
from harvesters.core import Harvester
from pathlib import Path
h = Harvester()
GENTL_FILE = Path.cwd().parent / "./libs/s2i_GenTL_win64/GEVTLS2I.cti"
assert GENTL_FILE.is_file()
h.add_file(str(GENTL_FILE))
h.update()
ia = h.create()
Reproducable:
- [X] Yes
- [ ] No
Expected Behavior No crash as in v1.4.0

Reproducibility
This phenomenon can be stably reproduced:
- [X] Yes
- [ ] No.
If applicable, please provide your observation about the reproducibility.
Actions You Have Taken
- [X] I've read the Harvester FAQ page.
Additional context I suspect the crash might be due to events added in v1.4.1. It might be that my camera implements them incorrectly, but I'd expect harversters to not crash if I'm not using that feature.
