Issue with netedit: Error "SubTopic '' doesn't exist"

[usamael2000]

Hello everyone,

I’ve encountered an issue when trying to open netedit. The following error occurs:

$ netedit
Error: SubTopic '' doesn't exist
Quitting (on error).

To provide some context, I installed SUMO using Python in a virtual environment with the following steps:

python -m venv sumo_test
cd sumo_test
. bin/activate
pip install eclipse-sumo

I’ve tested multiple versions of SUMO (1.19.0, 1.20.0, 1.21.0), including the latest development version, but the issue persists. Interestingly, both sumo and sumo-gui are working without any problems.

If anyone has encountered this issue or has suggestions for resolving it, I would greatly appreciate your help.

Thank you!

OS: Debian GNU/Linux trixie/sid x86_64
