I investigated the problem a bit further. It isn’t a segmentation fault, but instead libc detects a problem, prints a stack trace and calls abort().
When using ‘--stack-trace-mode never’, gimp refrains from catching SIGBUS, SIGSEGV and SIGFPE, but it still catches SIGABRT, which isn’t then raised for apport to catch.
