Dear Maintainer,

Thanks for

    maintaining the cool package gimp and

    checking out my bug report.

I tried running gimp on bash's command line.

I expected gimp to display its graphical user
interface.

Unfortunately gimp immediately crashes with

    free(): invalid pointer

Here's a back trace from running gimp in gdb:

Feel free to let me know if you happen to have
any suggestions.

I wondered if a corrupt configuration file in
~/.config/ crashed gimp.

So I ran it as a different user with different
configuration files.

Unfortunately, it still crashed when run as the
root user.

Here's what I saw

    root:~ gimp
    The connection is closed
    free(): invalid pointer
    Segmentation fault (core dumped)

So I expect something other than a corrupt
configuration file is crashing gimp.

So,
Kingsley

I humbly attach the output of a debugging tool
called "valgrind".

Valgrind automates finding software bugs related
to accessing memory.

Like free().

I'm no expert, but I happened to notice the "ERROR
SUMMARY" at the end of the attached log file
mentions

    gimpextension.c:415

Thanks,
Kingsley
