Dear Maintainer,

I saw phototonic show up today and thought I would try it.
However it does not start. When run from the command line I get this:

krc@ken:~$ phototonic
*** Error in `phototonic': free(): invalid pointer: 0x00007f90369005a0 ***
Aborted
krc@ken:~$

There is no dbg package currently or I'd try gdb.
I have not tried it on other systems.

Hi Kelly,
 Does it remain the same after a full package update? You may try to
run it from gdb and see if you get more information. Do you have an
Intel or AMD CPU?
Does it crash if you supply a picture name as a parameter?

Cheers,
Laszlo/GCS

I have an Intel Ivy Bridge. All packages it depends on where up to date,

I have now gone ahead and updated glib/gtk/pango (had been putting them
off since I didn't want to restart X before). So everything is
updated. Still the
same error. Also the same error when giving it an image as a parameter.

I tried gdb:

Reading symbols from phototonic...(no debugging symbols found)...done.
(gdb) run

Thanks,

 Meanwhile I realized phototonic has a bad memory usage pattern. At
least valgrind reports so. You may try it as well and post the output.
Simply try 'valgrind phototonic' or 'valgrind --leak-check=full -v
phototonic'.

Yikes! Yeah, it is really bad it looks like.
