Re: [orca-list] Gnome 42

[Mike Gorse <mgorse alum wpi edu>]

I just ran into this, too. It turned out to be unrelated to Orca or 
accessibility and caused by evolution-ews, which is pulled in and still 
linked against gtk 3. If I remove evolution-ews, then gnome-contacts will 
start up for me. Here is how I debugged it, in case it is caused by 
something different in your case:

- Start gnome-contacts under gdb.
- Break on main.
- Once main is hit, set a breakpoint on dlopen.
- After each call to dlopen, try to set a breakpoint on gtk_misc_get_type. 
It is one of the old symbols that gtk 4 checks for to determine whether 
gtk 3 has been loaded. If this succeeds, rather than gdb telling you that 
the symbol is not defined, then you've found your library that pulled it 
in.

Hth,
