Summary0002321: crash when copying a region
Descriptionongoing@3484

this one is not easy to explain, cause i am not 100% sure what exactly i clicked when the crash happened.
i wanted to copy a region with the 'ctrl+middle click' so that i end up with two regions in two tracks, which are at the same position in the time line.
but the shortcut did not worked the way i expected (for what ever reason).
so than i was thinking that i am using a wrong short cut, and i tried several others, like ctrl+leftclick, shift+leftclick, shift+middleclick, searching for the right short cut. doing this, at one point ardour crashed. i am 99% sure that at that moment a was clicking either ctrl+leftclick or ctrl+middleclick.

rev 3486 has a fix for this crash, i believe. it seems to be quite an old problem. whenever a RegionView object was copied, it copied the editor pointer, which could point to a real, live widget (or not). this was the wrong thing to do.
