Created attachment 144682 [details] steps 1 to 5 of reproduction steps ### System information OS : Fedora 28 package : libreoffice-impress.x86_64 1:6.0.6.2-1.fc28 (official Fedora package) So far, haven't tested any other OS/version ### Reproduction steps The attached file contains the steps 1 to 5 1) Open a new Impress presentation 2) Create two text zones (let's call them A and B) 3) Type some text in zone A 4) Insert a bullet list in zone B (Format > Bullets and Numbering… > Ok) 5) Add some text in zone B, with at least 2 list elements 6) Select all the text in zone A 7) Copy it (Ctrl-C) 8) Select all the text in zone B (spanning over several bullet list elements) 9) Paste as unformatted text (Ctrl-Shift-V > unformatted text > Ok) From there, the whole program becomes unresponsive (even the last Ok button visually remains pressed), while the LibreOffice process uses 100% of a CPU core until killed.
