Subject: Fix a crash due to Inset**::mouse_hover_[] containing an invalid pointer to a BufferView.
X-Git-Tag: 2.0.0~3295
X-Git-Url: https://git.lyx.org/gitweb/?a=commitdiff_plain;h=b269eb9117b299b5485488befbe9ad9a2b9b7ecd;p=features.git

Fix a crash due to Inset**::mouse_hover_[] containing an invalid pointer to a BufferView.

Clear the mouse_hover state when closing the BufferView. Otherwise, there will be an invalid pointer stored in the Inset and crashing LyX when the Inset's destructor is called.
