Hi all,
recently I discovered a segfault in enblend. It is a fairly big project,
so i can not *simply* provide input images or the whole core dump, but
here's a stacktrace:

enblend version is
$ enblend --version
enblend 4.1-cd12da20db1a
Recent version of the Ubuntu PPA.
Solved the issue for myself by splitting the project up to 4 smaller
images, then manually blending those in gimp. Is it just a memory issue?
But then I'd prefer a bad_alloc over a segfault :)
Can I provide further information to solve the bug?
Thx,
Benjamin
