Guiu,
go to partha.com and download the right executable.

The one you downloaded is the first compilation of 2.8 (which contain the bug). Partha build is patched against this bug - so look at partha.com for GIMP 2.8.1

Hello Gimp !

I've found a problem while using GIMP Portable 2.8.0 for windows downloaded from portableapps.com

The problem is that gimp shows 1.3GB as the size of all images. I've noticed this wrong behavior when clicking preview when I export an image. It also happens in the open file dialog ( only in the preview column ). In the open dialog gimp is not showing preview but I guess that the wrong size is causing that because GIMP thinks the file is too big to make a preview.

A little summary: GIMP Version: 2.8.0 Portable
Repeatable: Always ( tested on 2 different computers ) OS: Windows
Problem: GIMP shows all files size as 1.3GB Steps:

1. Open GIMP
2. Go to Open file dialog
3. In the folder navigation column it shows the real size of the image, in the preview column it shows 1.3GB

1. Open GIMP 2. Create an empty image.
3. Export in jpg
4. Check "preview in image window"
5. Image size estimation is 1.3GB

I've noticed more problems, but there are not as clear as this one and I'm going to take a little time to identify exactly in what conditions they happens. I hope that report is concise enough :)

Greetings Guiu Rocafort

I'm actually very novice yet and my knowledge on GIMP internals is pretty limited. So, those more expert developers: What do you think ? Would it be difficult to compile GIMP with gprof ? Would it be really useful for improving GIMP performance ?

The first steps should be a research in the mailing list archives and in Bugzilla to identify and verify known causes of performance problems:

The bug report is

The changes to prevent it are described in https://bugzilla.gnome.org/show_bug.cgi?id=669818#c28 ff. but there's no verification whether this is considered a fix or a workaround.

True, is not a GIMP bug is a GTK bug but Partha compilation ( with 2.8.1 which is not an official number probably ) solve that problem
and sometime users just need something to work..

I've tested the executable under WIndows 7 and I can confirm that the problem described by the Guiu is gone.
