GIMP on Jessie causes total freeze

I've encountered a problem with GIMP on Jessie. It causes total system freeze with latest available kernel, but not with the previous. This can be reproduced on at least 2 PCs.
I've tried to file a bug via reportbug, but it returns error 500.
What are my further steps?
uname -a:
Linux debian 3.16.0-8-amd64 #1 SMP Debian 3.16.64-2 (2019-04-01) x86_64 GNU/Linux

gimp -v:
GNU Image Manipulation Program version 2.8.14
git-describe: GIMP_2_8_12-2-ge62e6fe
