Very unlikely, but the important thing is to get a proper full
backtrace, as then there is no need to make assumptions ...

I can't make any useful deduction from the above, a warning is expected
here, till you (the guix team) fix it, let's set this env var, and
concentrate on the cause of the segfault ...

this gdb backtrace 'preamble' is, to me, useless as well

I won't be able to help you help Guix track this problem unless we get a
useful backtrace, so much as because i probably will need it to ask for
some help from upstream devs ...
Could you ask for some help from guix to produce it?

Yes, i did expect this and wanted to show you ... you don't see
any g-golf trace here because it fails in the gtk engine, as i
understood so far, before it can't find the derived class snapshot
vfunc.

ps: you did not answer my quiz about your guix host distro - i
would like you to - at least temporarily - manually install g-golf
there and see if everything works fine ... Could you do that? thanks
