Bug#948380: GIMP crash with floating point exception on image save.

[Bernhard Übelacker]

Dear Maintainer,
when comparing with a process while having debug symbols
installed, I guess the given backtrace would translate to
something like below.

Therefore I guess this crash is the same
as described in #929113.

Unfortunately I could not find a matching appearance of
function gimp_projection_chunk_render_iteration.

Additionally upstream has highly modified this file already.

Therefore, if this is reproducable, running with installed debug
symbol packages "gimp-dbgsym libglib2.0-0-dbgsym libgimp2.0-dbgsym" [1]
and an attached gdb, issuing at the crash the commands 'info reg'
and 'thread apply all bt full' could give some more insight.

Kind regards,
Bernhard
