Description Roman Gilg 2018-01-18 10:41:44 UTC
Try to edit the name or path of an entry in Places sidebar. Does not change on pressing Ok.

master branch - Neon dev unstable
Comment 1 Nate Graham 2018-01-18 15:23:08 UTC
Could not confirm as of git master yesterday. Can confirm after a pull and build, which includes all the 17.12 work that was just merged to master. Probably fallout from some of Renato's work.
Comment 2 Roman Gilg 2018-01-19 09:57:44 UTC
The situation just got worse. After multiple edit attempts I gave up and later rebooted. Now Dolphin segfaults on launch. Backtrace shows that it is related to the PlacesItemModel:

Comment 3 Kai Uwe Broulik 2018-01-19 10:18:05 UTC
Editing in file dialog (using KFilePlacesModel) works fine and is reflected in Dolphin immediately. Editing in Dolphin briefly shows the new value but is then overridden by the old.
Comment 4 Roman Gilg 2018-01-19 10:42:21 UTC
The first bad commit for the seg fault is:

The first bad commit for the original problem (edit of places entries is not possible) does not seem to be introduced by Renato's patch though. At least on its parent commit I could observe similar problems on renaming.

I'll leave the segfault in here anyway, because it both from all we know involves the PlacesItemModel in some way.
