Thanks for the bug report. The crash is bug 259089, but it would be interesting what the cause of the freeze is because it is definitely due to a different problem. Is the issue reproducible for you? If yes, it would be great if you could try to create a backtrace at the time of the freeze and post it in a new bug report (continuing the discussion about the freeze here might cause confusion because the KFileItemActions crash backtrace is already here, and this bug report will show up in queries that are related to this crash). Please see

https://community.kde.org/Dolphin/FAQ/Freeze

for details. Thanks for your help!
