What are your settings in translation memory ?

Can you send a screenshot of the tooltip before you right click and Delete the entry ? It should display the filename and the TM name.

I think the string message in the confirmation popup is has some null because of a special situation either in the TM name or the target string.

I tried to reproduce the situation, which did not really succeeded. I copied a .po file, nl/messages/qt/libphonon.po, to a new name nl/messages/qt/libphonon_test.po. Tried to enter this file in the TM, which did not seem to succeed. Removed that file and opened the original in the edit window.
Selected an item and clicked right on the item in the TM sub window.
See scherm.png
Selected "Dit item verwijderen" (Remove this item) and got
see Screenshot_20190206_112249.png
Pressed Ja (Yes). No crash.
I selected another item, hoovered on the item in the TM sub window and got Screenshot_20190206_112855.png which shows, "Is niet meer aanwezig in het bestand" (No longer available in file), however clicking right and selecting Open file opened the mentioned file.
