Echando un vistazo a la l\u00ednea que produce el problema se puede ver que al intentar obtener los valores de ident<\/b>, path<\/b> y profile<\/b> encuentra m\u00e1s componentes a separar de los que espera. Lo primero que se me ocurri\u00f3 es mostrar informaci\u00f3n de las l\u00edneas para ver qu\u00e9 estaba pasando:<\/b><\/p>\n

for line in data:
\n  if (not line):
\n    continue
\n  print line<\/span>
\n  ident, path, profile = line.split()
\n  […]<\/p>\n

Con esto se puede ver las l\u00edneas de las que est\u00e1 intentando leer los valores que busca:<\/p>\n

Hay alguna aplicaci\u00f3n que lanza internamente gDesklets<\/b> para ver la lista de componentes que tenemos cargados que en lugar de mostrar solo lo que se le pide muestra tambi\u00e9n una cabecera con la licencia. En la GPL<\/acronym>\u00ab>GPL<\/acronym><\/a> hay una parte que dice que si haces un programa para consola, las primeras l\u00edneas de la salida est\u00e1ndar del programa debe mostrar un mensaje informando de que es software libre e indicando que no se ofrece ninguna garant\u00eda (si es el caso):<\/p>\n

TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

\n2.c If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.)<\/p>\n

Habr\u00e1 maneras seguramente m\u00e1s finas de hacerlo pero para salir del paso he a\u00f1adido esto al archivo \/usr\/lib\/gdesklets\/main\/DisplayList.py<\/b><\/p>\n
