Summary0004351: Crash when loading session; control protocol / theme issue?
DescriptionSVN r10187 crashes with segfault when trying to create a new session or open an existing one. Judging by the attached backtrace, it has something to do with loading control surfaces and the associated log message.

Could this be caused by a missing theme? ardour_ui_dark.rc seems to not be installed anymore after some changes in r10161 and r10162. I think somehow the "use_the_magic()" call on the new rc include processor got dropped in the second commit. Plus I can't find any install_path property for these rc files.
TagsNo tags attached.

In fact, after manually copying ardour3_ui_dark.rc to the SYSCONFDIR, it starts up alright. So there are really two issues here:
1. Gtk rc file not installed
2. Crash in message display code (?) when ardour theme is not found

If 2. is not easily fixed, Ardour should probably bail out completely if the theme is not found, instead of just warning that it 'might look weird'.

I ran into the same issue, same backtrace. Then I found this bug, which though identical I'm uploading the backtrace anyway...

 Attached is a patch that installs "ardour3_ui_dark.rc" and "ardour3_ui_light.rc"

ardour3_ui_dark.rc contains the contents of:
ardour3_dark_fonts.rc
ardour3_dark_styles.rc
ardour3_widgets.rc

ardour3_ui_light.rc contains the contents of:
ardour3_light_fonts.rc
ardour3_light_styles.rc
ardour3_widgets.rc

(the include lines are textually substituted by waf)

I know the current build process packages ardour3_widgets.rc, but should it also package? :
ardour3_dark_fonts.rc
ardour3_dark_styles.rc
ardour3_light_fonts.rc
ardour3_light_styles.rc

The error (segfault in insert_with_tag) occurs because ptag and mtag are null.

ptag and mtag are null because the error message happens before load_rcfile() is called, and so info_ptag/info_mtag are yet to be defined.

Patch applied to SVN 10189. Thanks!

Actually, when ARDOUR_UI is instantiated at the very beginning from "Gtkmm2ext::UI::run" it creates a new ThemeManager which calls setup_theme()->load_rc_file()->Gtkmm2ext::load_rcfile() but load_rc_file never runs load_rcfile because it isn't available.

load_rcfile is necessary to define the gui elements required by the startup info message "looking for control protocols". When that message occurs ptag and mtag are null, so the program segfaults.

I think either
1] Gtkmm2ext::UI::process_error_message needs to be fixed so it can work without an rcfile.
2] rcfile not found should be a fatal error
3] All messages should be transmitted to the text/console receiver if the rcfile is not found

this was fixed about a month ago so that messages delivered before the tags used by the log window are defined are simply printed to stderr.
