The context menu for formrichtext.xml show items that didn't work and crash the different LibO applications. Suggestion is to update the context menu with stuff like in drawtext.xml if the functions didn't crash LibO.
Same crash happens also when using the toolbar. I filled a bug about it - Bug 120750.
Andreas, can you please be more descriptive to reproduce the crash? Which toolbar or context menu of which file format and which command is affected?
