Porting the decompose/compose plugin

Hi there,

i'm currently porting the decompose/compose plugins to use babl, but i'm bumping into the following error:

decompose.c:

Including "babl/babl.h"

and simply defining

const Babl *rgb = babl_format ("RGB u8");

in the function extract_hsv without doing anything else brings me to:

fatal error: segmentation fault Gimp-Base-WARNING **: 4 tile managers leaked unref tile manager 0xa99e150 (900 x 595) unref tile manager 0xa991460 (900 x 595) unref tile manager 0xa869580 (900 x 595) unref tile manager 0xa991400 (900 x 595)

after using the plugin to decompose an image into HSV!

What do I have to do to stop the leaking? I don't see the connection!

Thx!

Alex

If the code seg faulted it wouldn't have had the chance to do proper clean up. From what I seen in the babl sources babl_format() allocates new memory. You need to call a routine to get rid of the structure when you are done with it.

Run your program with debugging enabled so you can get a backtrace when the code seg faults. If the code is seg faulting when your program is terminating it might be due to your not having called babl_init(). I'm not an expert on babl so I could be a little off here. You should check the babl docs or talk to Pippin (on IRC).
