Hi Enrico and Andreas,
Segmentation fault scenario for r714 looks like this:
If I use the old geany.conf (from e.g. r712), I get a segmentation fault. When I delete geany.conf, geany starts OK and re-creates
geany.conf. I do not remember modifying geany.conf, but I attach it all the same. I used the -c switch to toss files around to find the cause. Hope this info would be useful, but it does look like a quirky on-off case in otherwise very stable and delightful editor.
