When the i/o channel spinbox widgets are realized, they call
print_channel_count(). A "0" is formatted as "all available channels".
This causes the GTK::Entry inside the spinbox to emit a "changed"
signal which in turn triggers a parameter_changed(), [..], store_state(),
which calls into the spinbox again while it is being realized,
which makes gtkmm barf.
Start Ardour with JACK running (autoconnect to jack), Window ->
Audio/Midi settings -> initial no_control_notebook. Change
Audio System -> [control widgets are realized] -> glibmm std::exception
I can't see a reason to select the newly-created regions after
splitting selected regions: I can't think of any case where you'd want
the next operation to apply to both the regions, and it makes it very
easy (in my experience) to trim/move/&c. both regions afterwards by
mistake.
However, this behaviour is desired for Mixbus, so make the selection of
regions after a split of selected regions dependent on
Profile->get_mixbus() for now.
./waf i18n warns about passing an empty string to _(). Actually, the code
in question just wants to make a label not appear, so it might as well
just hide or show it as appropriate rather than attempting to set its
text to the empty string.
Session templates are directories: use find_paths_matching_filter() rather
that find_files_matching_filter() to search for them. Fix a tiny comment
typo I spotted along the way too.
Move control-surface editor-window management to the control surface.
The Preferences-Dialog is not aware of session specific or surface
specific actions and cannot properly manage the window.
