SVBONY 705c driver crash on indiserver start

[alfiolocastro]

Describe the bug Driver indi_svbony_ccd crashes as soon as indiserver starts. On a freshly installed i7 laptop Driver worked fine one time (just few capture and streams), then I changed USB port. It crashed all the time since then as soon as indiserver stars.

To Reproduce Exact steps to reproduce the behavior.

1. Start Kstars and Ekos once, indi_svbony_ccd device driver starts and works fine
2. Close Kstars, change USB port for the 705c, restart Kstars
3. See error (all the subsequent attempts)

Desktop (please complete the following information):

• OS: Ubuntu
• Version 22.04.03 LTS

Some updates: looks like the crash is related to the SVBONY config files under .indi directory. When there's a config file present driver crashes and if I delete it, it starts (until next time because file is being regenerated every time)
