Hello , I was very interested in the bug reported for check printing in Debian Buster. I am running Gnucash on Raspian Buster on the Raspberry Pi 4 and check printing crashes Gnucash 3.4.1.
Linux aa5kv 4.19.93-v7l+ #1290 SMP Fri Jan 10 16:45:11 GMT 2020 armv7l GNU/Linux I will report this bug to Raspian and provide the bug report number in Debian. Hope we get this fixed soon, although I understand it is resolved in 3.5. Thanks, ---John Stewart
