Excellent! Well, not excellent that you got a crash, but that you at least can now debug it. And I don't have to install gdb now :-) I should also mention something else really odd. I confirmed bug #1790 as fixed...but it is not fixed for note-down-crash.rg. This one still opens with the Draw tool selected. However, other similar sessions that I randomly picked, opened with the correct tool. Even the other crashing session that note-down-crash.rg was distilled from opens OK...But note-down-crash.rg...
Dang!! It still crashes on the latest master [258be1], so it's not that. I guess it's gdb next.
Now I'm surprised. I had already taken into account the Rosegarden.conf by not only avoiding my own, but starting RG with basically a fresh install i.e. nothing with rosegarden existed in either ~/.config or ~/.local/share. That gives me a "Welcome to Rosegarden" screen at start up and RG creates its own config directories. @tedfelix mentioned something about the NotationEditor maximizing. However, like you, that does not happen for me. Just so you don't feel left out. I have many sessions where...
I knew this was going to be trouble (much like bug #1792). A devious bug. I think it involves a seemly innocent "set up for the crime" first, then when you do something innocuous later, bam! For the report I had tried to remove what seemed like superfluous, preposterous keystrokes to keep things simple. Now, forget all that. You get the note-down-crash.rg with the bug imprisoned, and which is exactly what I used. The instructions are simple enough this time: Open RG on the note-down-crash.rg file...
NotationEditor crashes undoing a raise or lowering of repeated segment notes
Doubling note length increases segment length by 7+ measures
No, not annoying. It just confused me for a while seeing something labeled XML and not a single XML tag in sight :-) I don't think there's a need for an extra option. If annoying, the clear recent list option takes care of that now.
The commit in the pull request does fix the refresh issue. However, it does not restore the original selection. The original refresh still does not work for me in [94f7ef]? I tested it three times. I too get some other track selected (track #1) in this case, but the instrument panel still shows #4 selected as though no refresh occurred?
