Can't export xml (nor any other format) from kdenlive 24

[cervier]

Windows 11. Exported a short project from DaVinci Resolve in FCP7 XML, opened it with no problem in kdenlive. But when trying to "Export OTIO", there were problems with "docversion", then with "time", then... I changed the script following ChatGPT advice (eg replacing line 248 with if docversion and float(docversion) < float("1.1"):, or changing the time function) but still got

Hi, the new version of kdenlive (25.04.0) supports OTIO natively, could you try using that instead? You should be able to export an .otio file from Resolve, and then open it in kdenlive directly with the "File/OpenTimelineIO Import" menu.
