[Gimp-developer] segmentation fault when trying to replace deprecated functions in lcms.c
When I try to call the recommended new functions to replace the deprecated functions in the lcms.c plug-in, the code segmentation faults. To illustrate the problem, I wrote a line of code to call 'gimp_drawable_get_buffer' and put a printf statement just above and below: printf(lcms: lcms_drawable_transform: before call to GeglBuffer\n); GeglBuffer *buffer = gimp_drawable_get_buffer (layer_id); printf(lcms: lcms_drawable_transform: after call to GeglBuffer\n); The code segmentation faults when it gets to GeglBuffer *buffer = gimp_drawable_get_buffer (layer_id);. Although I am not experienced in interpreting backtraces, and could easily be completely wrong, it looks like the problem is that babl doesn't accomodate the file format RGB u16: #6 0x7f216af03c2f in babl_format (name=0xb50610 RGB u16) at babl-format.c:667 line 667 is the end of babl-format.c and RGB u16 does not occur anywhere in babl-format.c. I am not sure how to fix this problem.

Do you call gegl_init()? Look at file-pat.c or goat-exercise.c for simple examples of gegl-enabled plugins. --mitch On Thu, 2012-09-06 at 12:59 -0400, Elle Stone wrote: When I try to call the recommended new functions to replace the deprecated functions in the lcms.c plug-in, the code segmentation faults.

Thanks! gegl_init() enabled the plug-in to run without segmentation faulting. Now to see if I can actually replace a deprecated function or five!

Re: [Gimp-developer] history of great bugs
hi, If you want a fun bug, Id say the drag-and-drop ghost in 2.4 series(I think it got fixed by 2.6?) takes the cake. It eluded people for a while... I think it was Michael Mure before his first GSoC who found the issue...

Re: [Gimp-developer] Reviving Tito (The menu search tool)
Hey Alexandre, git pull g...@github.com:ssrihari/gimp-tito.git tito make make install Merges and builds fine for me. Please ensure that you pulled from the* tito branch.* If it still fails, could you please let me know what the problem is? it was unable to locate GEGL Could you elaborate on this?
