Segfault on deleting an image while in the image editor See steps to reproduce below and backtrace (4.130.0.1.fc23 on x86-64) Reproducible: Always Steps to Reproduce: 1. Open an image 2. Click for the image editor 3. Select a rectangle area 4. Crop to the area 5. hit delete Actual Results: Seg fault - see backtrace below Expected Results: No crash; either it ignores the delete or it deletes it and closes the editor. #0 0x00007f5d1a331a17 in

(In reply to Gilles Caulier from comment #1) > > > *** This bug has been marked as a duplicate of bug 222974 *** Are you sure that's the write bug to dupe to - that was closed having been fixed 5 years ago; this is a failure on a current release.
The problem is relevant of KDirWatch from KDELibs. Look well old bug.
(In reply to Gilles Caulier from comment #3) > The problem is relevant of KDirWatch from KDELibs. Look well old bug. But since that bug was marked closed/fixed in 4.4 it doesn't sound right to dupe my bug to it, since it's happening on 4.13
(In reply to Gilles Caulier from comment #3) > The problem is relevant of KDirWatch from KDELibs. Look well old bug. Where is the mention of KDirWatch in the stacktrace? The original bug had: #6 0x00007f3337b2b10b in findSubEntry (path=<value optimized out>, this=<value optimized out>) at /usr/src/debug/kdelibs-4.3.87svn1070744/kio/kio/kdirwatch_p.h:161 There is no mention of either KDirEntry or findSubEntry in this stacktrace. Moreover, according the reproduce, it happens now with an easy reproducer. Can you please reconsider?
This cannot possibly be a duplicate of bug #222974, because (as pointed out by the reporter), that bug was fixed in 4.4.1 and this bug was reported against Fedora 23, which ships kdelibs 4.14.12.
Look on duplicate bug. There a few files with similar backtrace where KDirWatch is present. There is no reason to see digiKam crashing while deletion of file. There are plenty of reports relevant of file deletion and KDirWatch. When a file is removed, KDirWatch detect changes from hard drive to update database.
