Selecting a a set of image thumbnails, then selecting "Group Selected by Time" in the context menu, creates as many tasks as images selected entitled "Editing group", which then stay at 0% progress, and cannot be cancelled. Reproducible: Always Steps to Reproduce: 1. Select some images in thumnail view. 2. Select context menu "Group Selected by Time". 3. In a few moments, detailed progress window will show multiple non-progressing "Editing group" tasks. Actual Results: No images are grouped, queued tasks cannot be cancelled, when exiting digikam, "Unfinished tasks" dialog appears. Expected Results: Selected images are grouped by time. This bug appears very similar to Bug 295263, which was fixed for 2.6.0
With respect to bug 295263, in which also the queued tasks failed to progress, I have found that selecting an image group, changing a tag, and choosing "Apply to all versions" rather than "Apply" (where problem was fixed) results in the same non-progressing tasks behaviour. I don't know if bug 295263 should be re-opened, but thought it relevant her because the problem relates to image groups.
Git commit eeb0c74b385d3c220dce8fba7167644a67add6d7 by Marcel Wiesweg. Committed on 17/07/2012 at 21:50. Pushed by mwiesweg into branch 'master'. Creating a task with 0 items would introduce a progress item which never finishes. Generic fix and for the special case of group by time.
