Start with OPMLDataSource.kt at line 16 and the saveToDatabase flow in OpmlService.kt around line 186. Reproduce the failure using the Akregator OPML import and inspect the parser expectations shown in the stack trace. Done means a compatible Akregator OPML file imports successfully without the reported OpmlParseException.
