 * GimpDebug simply displays a dialog with debug data (backtraces,
 * version, etc.), proposing to create a bug report. The reason why it
21 22
 * is a separate executable is simply that when the program crashed,
 * even though some actions are possible before exit() by catching fatal
23 24
 * errors and signals, it may not be possible to allocate memory
 * anymore. Therefore creating a new dialog is an impossible action.

 * So we call instead a separate program, then exit.
