Ouch. I'm very sorry, I do get your problem now. I must have taken the error message (due to no CHF/$ transactions) as the report...Really? I hardly believe it, because this bug is present with all versions of gnucash and all linux distributions I tested. Please send a screenshot. I attach my one with the problems marked.It's showing as expected with de_DE and de_CH.Please try "Berichte -> Aktiva & Passiva -> Reinvermögen Balkendiagramm". What does the title read? My system only shows "Reinvermgen Balkendiagramm", the umlauts are still missing... What is showing on your systems?
I haven't had much success in poking around yet, either.
Again, my apologies for this misinformation.
Kind regards
