While pasting some information into a power point document, the document is closing by itself. can anyone suggest the solution?

edit

Do you really see the document closing and LibreOffice application still running?

The solution:

1. File a new bug report.
2. In the report, provide exact steps needed to reproduce the bug (including LO and OS versions, the specific information pasted into the document (its source if needed), and where and how it's pasted - e.g., using toolbar/context menu/keyboard shortcut etc; if this is only reproduced in some existing document - then attach the document).
3. Wait for a bugfix; if asked, provide necessary clarifications.
