Fwiw I love the plugin... I just don't like the crash :/
from geany-plugins.
Overview plugin uses Scintilla to generate the overview, but there have been no changes to the plugin for many years, but IIRC there have been changes to Scintilla, some of which may be incompatible with such old code.
As nothing has been heard from the "maintainer" of the overview plugin its probably unlikely it will be fixed unless "somebody" does it, or the plugin is shown to be the cause of a crash it may be dropped if nobody cares for it.
from geany-plugins.
FWIW I can confirm the crash, and got this GDB backtrace and Valgrind log:
GDB backtrace for the crash (nothing new though)

I however have for now no clue what the issue is or even where (is it Scintilla doing something problematic with multiple concurrent views, is it a timing bug in IBus or GTK?).
from geany-plugins.
BTW, somebody motivated enough could try and find what broke this plugin, it could help debug the issue. Be it testing various Geany versions or even better, using git bisect
.

@l33tlinuxh4x0r in this context "care" means "does the work to fix it", as in care and feeding, not just "like" it 😁

If I had the skills I would fix it, however I don't so hoping that someone else will take this up.
