I've found a bug in the current CVS tree:
- make a screenshot (File->Aquire->Screenshot)
- save it as a jpeg
- close it
- make another screenshot
- save it as a jpeg -> segfault.
After some investigation, this is due to the comment code.
The default comment is corrupted the second time.
More precisely, gimp->config->default_comment is corrupted.
I've put a g_print() in get_default_comment_invoker() in order
to watch this.
Though, I've been unable to find where this value is changed.
