Hello Michael Hatzold, I tried to have a look and guess gimp received from some plugin feedback in form of a malformed GIMP_PDB_INT16ARRAY.
Unfortunately this may not be enough information for the maintainer to fix it. Could you please provide more details on which exact steps you took to trigger that crash? Also when forwarding such backtraces it would be highly appreciated if you could consider installing the debug symbols for the crashing application, e.g. gimp-dbgsym. These packages are contained in a special debian repository [1].
