Hello Guenter Grodotzki,
I am not the maintainer for tilda, just got here and
tried to collect some more information.
For some reason your upstream report contains one
(interesting) lines more than made it into the debian report.
Just as a hint: the real important information has to be
queried from gdb by the "bt" or backtrace command.
For bug reports sometimes "bt full" might be helpful too.
Adding the debug symbol packages [1] would be even more helpful.
I have tried to reproduce in a minimal amd64 buster VM.
Tilda just run fine within a openbox or plasma X11 session.
I just received a crash when running within a gnome session:

At least the address offset from my frame 0 and your frame 0
is equal, therefore I guess you are running also
a gnome/wayland session?
This issue are describing in more detail
upstream issues [2] and [3].
Kind regards,
Bernhard
