Committed on 04/11/2025 at 20:48. Pushed by johanneszarl into branch 'master'. Don't updateCell for a new thumbnail Here's another scenario that logs "dataChanged() called with an invalid index range": * start a fresh demo * open the thumbnail view * add at least one new image in the demo folder * rescan for new images - the message is logged once per new image This patch only triggers dataChanged() when a thumbnail is updated, not when a new thumbnail is inserted into the cache.
