Comment 1 John Choate 2016-01-14 01:19:19 UTC

See if doing the following in Dolphin helps:
Configure Dolphin > Services > Uncheck 'File to activity linking plugin'.

Plasmashell and dolphin have not crashed when hovering mouse in the context menu since I did that. Perhaps you are having the same issue when right-clicking on icons.

Comment 2 Frank Reininghaus 2016-01-26 06:20:26 UTC

Thanks for the bug report. This will be fixed in Dolphin 15.12.2. As a workaround, wait some time before you click "Configure Dolphin" after moving the mouse pointer there. The crash only happens if there is a submenu (like Extras or Help) open while you click.

> Testing out a custom service menu. Also crashes when I try to configure it under Configure Dolphin

You backtrace seems to be about the "Configure Dolphin" issue, so I'll mark your report as a duplicate. If you still see the context menu crash and comment 1 does not help, please file a new bug report and provide a backtrace for that crash.
