Package: calibre Version: 3.26.1+dfsg-1 Severity: important Dear Maintainer,
When using Calibre with Turkish UTF-8 locale, Calibre UI fails to start. If it's a first install, welcome wizard is displayed correctly, but after completing the wizard, the UI fails. The calibre process stays in the background. To remedy the issue, user needs to set locale to en_US.UTF-8 before startup. Reproducibility: 100% (Every time) Reproduction steps: 1- Set system locale to tr_TR-UTF-8 2- Install Calibre 3- Start Calibre 4- (If needed) complete the welcome wizard. 5- UI crashes, traceback is shown. Closing window hangs Calibre process in the background. 5a- Subsequent starts (even after killing the process) will fail with the same error. Expected behavior: 1- Set system locale to tr_TR-UTF-8 2- Install Calibre 3- Start Calibre 4- (If needed) complete the welcome wizard. 5- Calibre starts, and functions as expected. Temporary workaround: - Set process' locale to en_US-UTF-8 Traceback: calibre, version 3.26.1 ERROR: Startup error: There was an error during calibre startup. Parts of calibre may not function.
